I'm working on a survey questionnaire using xlsform for ODK. Where I'm stuck: I have a questions on the from like this: 21. Are you willing to pay for the service if it was offered at $100? The answers can be either Yes, No, or Dont know. If the respondent says Yes, the next Question will need to add $20 to the previous $100 so the question should now read as: 21. Are you willing to pay for the service if it was offered at $120? This should continue until the respondent says No. How can I implement this using xlsform design?
I understand that you need a repeat select_one loop that goes until No is selected. There is a way to do that through the indefinite-repeat XLSForm.
This is an application of it to your question:
Explanation:
The count variable is keeping track of how many times your form repeats your question.
The repeat_count field in loop_question states that your repeat should go on if (i) the repeat has ran zero times, or (ii) as soon as the answer "no" is registered in willing_pay.
The variable amount calculates the amount you should be showing in willing_pay.
Hope this helps.

I have three seperate SPSS files with information about roughly 7500 hemicolectomy patients. One file contains the information about the hemicolectomies, the second one about other surgeries the patients have had during their lifetime and the last one contains information about their sick leaves during their lifetime.
I have merged (idnumber is the common variable) the files to a single SPSS document but i ran into a problem with filtering out the surgeries and sick leaves that have nothing to do with the hemicolectomy. I'm quite new to SPSS so the simplest way i could think of doing this is by somehow copying the hemicolectomy info to every case and then just using the date/time calculator to choose which sick leaves and surgeries to discard. Switching to wide format is unpractical due to the large number of unrelated surgeries and sick leaves: I'd have thousands of variables.
So basically I'd like to do the following:
IF idnumber = idnumber THEN variable1=variable1 AND variable2=variable2 etc
How would I go about doing this?
All help will be appreciated!
the IF command can only be used with one transformation:
IF [condition] [transformation].
Assuming both of your files are sorted by idnumber:
UPDATE file=[master_file_reference]
/file=[secondary_file_reference]
/BY idnumber.
EXECUTE.
The file reference can be made either by their dataset name, or by their full path.
More on the UPDATE command:

I cant comment yet, so Im sorry if I misunderstand the problem. I wouldve asked for clarification in the comments to the question... here goes...
So you have three sources of data which have dates (?) of hemicolectomies, one for each case; dates (?) of other surgeries, multiple for each case; and sickleaves even more for each case. Is that right?
I'd try solving the problem before matching all three file by matching the file that contains one observation per patient (presumably hemicolectomies) to the one with the second most observations (presumably other surgeries) per patient with the /table keyword:
MATCH FILES /FILE= 'surgeries.sav' /table = 'hemicolectomies.sav'
/by idnumber.
EXECUTE.
this will "fill up" the blank cells for each patient with the hemicolectomy data.
now use the datetime to check which surgeries "belong" to the hemicolectomies, thus reduce your data and match it to the sickleave data using the /table keyword again.
Seems like the easiest solution to me.
I am trying to update the textbox for the current request that I have opened. After making changes to the bound textbox (regardless of the record number current being edited) it modifies the tblVendorRequests.VendorDiscussionNotes for the newest request created within the table.
My form is a Single Form
My record source for my form is a table (tblVendorRequests)
My textbox (txtVenConLog) is using tblVendorRequests.VendorDiscussionNotes as its control source
For instance, say I am trying to add notes "Hello World" to request number 242. Request 242's notes remain the same, but the "Hello World is added to the newest record instead (overwriting the existing text that was in the request).
I have done a good amount of searching on the topic, and have not found a satisfactory answer on why this would be.
Any ideas would highly appreciated!
I redesigned my form to split the functions into 2 separate forms and that seems to have resolved the issue. I believe the issue was that when I 'opened' a record, it was not behaving like it would if the record-opening function resulted in calling a form to open with specific criteria.
I'm trying to scrape the price from the first ticket here page using this xpath:
'.//*[#class="price"]/text()'
This works in the developer's console, but not when I run it in the scrapy shell using response.xpath. I have also tried to following in the shell:
'.//*[#class="initial"]/div[#class="price"]/text()'
and
'//*[#id="tVB901769989"]/div[1]/div[4]' (although I don't think that the id property can be used in the shell like this).
Is there something wrong with the xpaths that I've used, or is there some thing different with the way the page works? Any help would be appreciated. Thanks!
this happens because you are checking at different requests, the page you see doesn't have the information you need inside that file, but it gets it dynamically, in this case from: www.vividseats.com/javascript/tickets.shtml?productionId=1771684
There you can check the prices on json format, I think this is for one item:
{
"s":"Section 111",
"r":"8-22",
"q":"4",
"p":"692.00",
"i":"VB782041491",
"d":"111",
"n":"Zone Seating. The seller is committing to procure these tickets for you upon receipt of your order. After you place your order and your order is confirmed, we guarantee that your tickets will be within the listed zone
or section listed or one comparable and that you will receive these tickets in time for the event or
your money back. Orders exceeding four tickets may be split up into different rows within the requested
zone or section.",
"f":"0",
"l":"Section 111",
"g":"0",
"e":"0",
"h":"07/21/15",
"t":"0",
"v":"",
"c":"84352",
"z":"1",
"rhdn":"0",
"ind":"0",
"sd":"0"
}
where p contains the price.
Okay, I know this question has been half answered around here, but I'll explain in full and see if there maybe a better way to handle this then in just two parts.
I'm building an HTML5 voting site, that will close voting every half hour. And then open a new batch of voting.
What I need to do, is have the URL of this site be 'masked' ie:
have a random URL for it be generated that leads to the same location- so say I'm directing users to voting.com, I want them to only access it via the url votingstuff.com/hg67, and have that end portion be changed every half hour- and once the new url is generated, remove access to the site via the old URL.
I might add that after the user votes, I'd also like to close their voting access until the new URL is posted. AKA- everyone only gets one chance to vote.
Thoughts? Libraries to check out? Sites that do this? I know the randomization has been answered a few times, but usually it's a generator led to by a page, I want to START with a randomly generated URL, and not have a page that creates it as a function. I may have to write code that generates the page I guess?
Here is an approach I can think of -
You don't need to handle multiple URL's, you can achieve this on the same URL itself by enabling/disabling access to the URL content every hour.
You will need some action on your application/server side as well. For reference lets assume you have a PHP server running. You will need some table that holds a status setting for you, something like this -
Settings Table
id settingCode value
=============================
1 votingOpen 1
You will also need to setup a cron job on your server that will run every half an hour. The cron job's task would be to run every half an hour & change the value of the votingOpen to its inverse. So assume open your votings, initial value of the votingOpen field would be 1 i.e the first half an hour of voting starts.
Along with this you will start the cron job as well. Now what will happen is that after half an hour the cron job will fetch the value of votingOpen read it & if its 1, it will change it to 0 & if its 0 it will change it to 1. This will happen every half an hour on your server.
Now you need to make this votingOpen variable accessible on your client side code using a simple query to fetch its value. On each render of your voting page, on top somewhere you can check this value & if its 1 i.e true, you will write the logic to go ahead & show the voting page. But if its 0, you can redirect the user or show a different message on that page.
Lets say your voting happens on http://somedomain.com/voting, on the render logic of this page you can do something like this -
Voting View Logic
<?php
$votingOpen = {some database query that fetches the value from the database};
if($votingOpen) {
// your voting view resides here
} else {
// either redirect user to some other page
// or show some message like voting is closed on this same page.
}
?>
Limit multiple votes from one person
Normally the best way to handle this is a combination or registered user only vote + cookie/localStorage + IP tracking
But if you don't have registered user voting, you can still capture IP of user & allow only one vote per IP and you can also set a cookie or a localStorage variable in the users computer so he can only vote once.
Hope this helps.

I am trying to discover if there is away to choose multiple Material#'s (or PO and PO Line#'s) in Access 2007/2010 so that if I want to enter the same info for all of them then I can just do it once rather than having to look up each individual Material# and enter the info multiple times.
We import Material#'s of our product and the PO#'s and the PO Line Item#'s from SAP into Access. My job is to look through each material# and see if the Buyer correctly benchmarked the price from the quote to verify we got the proper savings amount from our vendor. There are alot of times when a single PO will have up to 50 lines on it all for different material#'s but their specs and prices will all be the same. So rather than having to enter the same comment for 50 different material#'s, I am trying to find out if there is an easier way to choose the 50 material#'s and enter the comment once for all of them. Please let me know if there is a way as it would save me alot of time and my Purchase Analyst who helped build our Access data base doesn't think there is a way but I think there must be some way to do it, whether a Macro or something else they haven't thought of.
Thanks for any help you can provide!
