Calculated Field Not Showing Value - Ms.Access - ms-access

I am creating a student report card in ms access and there are five texboxes which can either be fill totally or few of them can be left unfilled. I have applied a formula through expression builder to add all the values in those five fields and display the calculated result in that specifix textbox.
But the problem here is that the textbox is not showing the result untill all the values are filled. If any of those five boxes remain null, the calculated result wont show up.
Here is the formula
[mo1]+[mo2]+[mo3]+[mo4]+[mo5]
and being stored in [Totalmarks]
I have also tried using the update query but the result remain the same. kindly help in this regard. Thanks

Null plus anything yields Null.
You can use Nz Function to substitute zero for Null when adding the textbox values.
Nz([mo1], 0) + Nz([mo2], 0) + Nz([mo3], 0) + Nz([mo4], 0) + Nz([mo5], 0)

dude you might be using a calculated field in the expression builder. take the values from the actual data cell, not a calculated one
for example
amt xx
tax xxx
total = amt + tax
advance = yy
then,
balance = amt + tax - adv (this is correct)
balance = total - adv (this is wrong)
dont know the reason behind it, but it worked for me.

How to fix the error dividing by zero in my expression in visual studio reports?

I created report in visual studio.The problem is with dividing by zero in total fields.
I have one column with value 00:03:15 and another column with 00:00:00
I want to sum these columns and want to show me average value from first and second column.
I used this expression ( formula ) in my case :
=Format(
TimeSerial(0,0,
Round(iif(sum(Fields!N_INBOUND.Value)=0,0,
sum(Fields!T_INBOUND.Value/Fields!N_INBOUND.Value))
+
iif(sum(Fields!N_INBOUND.Value)=0,0,
sum(Fields!T_HOLD.Value/Fields!N_INBOUND.Value)
+iif(first(Fields!HANDLING_TIME_MEASURE_TYPE.Value)=2,
sum(Fields!N_INBOUND.Value-Fields!N_TRANSFERS_TAKEN.Value),0))
+iif(sum(Fields!N_INBOUND.Value)=0,0,
sum(Fields!T_CONSULT.Value/Fields!N_INBOUND.Value)
+iif(first(Fields!HANDLING_TIME_MEASURE_TYPE.Value)=2,
sum(Fields!N_CONSULT.Value-Fields!N_TRANSFERS_TAKEN.Value),0)))/count(Fields!PRESENTATION_NAME.Value))
, "HH:mm:ss")
I used this https://sqldusty.com/2011/08/01/ssrs-expression-iif-statement-divide-by-zero-error/ and looks like :
=Format(
TimeSerial(0,0,
Round(
iif(count(Fields!PRESENTATION_NAME.Value)=0,0,
(iif(sum(Fields!N_INBOUND.Value)=0,0,
sum(Fields!T_INBOUND.Value/Fields!N_INBOUND.Value))
+
iif(sum(Fields!N_INBOUND.Value)=0,0,
sum(Fields!T_HOLD.Value/Fields!N_INBOUND.Value)
+iif(first(Fields!HANDLING_TIME_MEASURE_TYPE.Value)=2,
sum(Fields!N_INBOUND.Value-Fields!N_TRANSFERS_TAKEN.Value),0))
+iif(sum(Fields!N_INBOUND.Value)=0,0,
sum(Fields!T_CONSULT.Value/Fields!N_INBOUND.Value)
+iif(first(Fields!HANDLING_TIME_MEASURE_TYPE.Value)=2,
sum(Fields!N_CONSULT.Value-Fields!N_TRANSFERS_TAKEN.Value),0)))/iif(count(Fields!PRESENTATION_NAME.Value)=0,1,count(Fields!PRESENTATION_NAME.Value)) ) ) )
, "HH:mm:ss")
But shows me an ERROR.Anyone who know how to fix that?
Your data is something like below, Correct me if I am wrong. At the Bottom I have added Total for both columns.
Note: You will have to take care of what type your column (T_INBOUND and N_INBOUND) return values.
Now to create a Total for T_INBOUND and N_INBOUND
To add totals for a column group In the tablix data region row group
area, right-click a cell in the column group area for which you want
totals, then point to Add Total, and click Before or After.
A new column outside the current group is added to the data region,
and then a default total is added for each numeric field in the
column.

https://learn.microsoft.com/en-us/sql/reporting-services/report-design/add-a-total-to-a-group-or-tablix-data-region-report-builder-and-ssrs?view=sql-server-2017
Once you have Total you can create create a Cell Either next to your Total or below Total and add expression as below
IIF(IsNothing(Fields!Total_N_BOUND.Value) OR Fields!Total_N_BOUND.Value=0,0,
Fields!Total_T_BOUND.Value/Fields!Total_N_BOUND.Value)

Error when runing query from form between two date from a form

I have a form called FirstInLastOut which looks as the image below.
Based on Name or badge number I want to search between two dates.
I am using the following criteria on the query:
>=[Forms]![FirstInLastOut]![StartDateEntry] And <=[Forms]![FirstInLastOut]![EndDateEntry]
This is given me results that include other months as well. Please see the query report below.
So as you can see in the image the numbers of the dates are falling with the the parameter but getting other months as well.
How can I make it so it will only select the dates between the date ranges?
SELECT FistClockInRaw.Badgenumber, FistClockInRaw.name, FistClockInRaw.lastname, FistClockInRaw.MinOfCHECKTIME, FLastClockOutRaw.MaxOfCHECKTIME, [MaxOfCHECKTIME]-[MinOfCHECKTIME] AS TotalHours, FLastClockOutRaw.QDate, FistClockInRaw.MinOfQTime, FLastClockOutRaw.MaxOfQTime, RawCompleteQuery.CHECKTIME
FROM RawCompleteQuery, FLastClockOutRaw INNER JOIN FistClockInRaw ON (FLastClockOutRaw.Badgenumber = FistClockInRaw.Badgenumber) AND (FLastClockOutRaw.name = FistClockInRaw.name) AND (FLastClockOutRaw.QDate = FistClockInRaw.QDate)
WHERE (((FistClockInRaw.name)=[Forms]![FirstInLastOut]![FirstNameEntry]) AND ((RawCompleteQuery.CHECKTIME)>=[Forms]![FirstInLastOut]![StartDateEntry] And (RawCompleteQuery.CHECKTIME)<=[Forms]![FirstInLastOut]![EndDateEntry]));
is the Query
I assume that the forms fields StartDateEntry and EndDateEntry are bound to fields of type date.
I also assume that you are only interested to compare the date part of those form fields.
So try this condition instead to assure correct date interpreting:
WHERE FistClockInRaw.name=[Forms]![FirstInLastOut]![FirstNameEntry]
AND RawCompleteQuery.CHECKTIME >= Format([Forms]![FirstInLastOut]![StartDateEntry], "\#yyyy-mm-dd\#")
AND RawCompleteQuery.CHECKTIME <= Format([Forms]![FirstInLastOut]![EndDateEntry], "\#yyyy-mm-dd\#")
A remark:
Be aware that every date field/variable always contains a time part too!
So your current logic comparing EndDateEntry with <= can cause trouble, because you would only get results of the end date having time values of 00:00:00 in the field CHECKTIME.
If any record of CHECKTIME contains the requested end date and a time part bigger then 00:00:00, it is not in the result.
To avoid that, you should use < and add one day:
And RawCompleteQuery.CHECKTIME < Format([Forms]![FirstInLastOut]![EndDateEntry] + 1, "\#yyyy-mm-dd\#")

SSRS report builder 2014 CDbl precision

I have some column in my report, calculated the Sum using this exepression :
=SUM(IIF(Fields!Type.Value = 0, CDbl(Fields!Amount.Value), CDbl(0.0)))
it works but gives me the sum with no precision.
is there a way I can view the Sum with precision?
UPDATE
the Fields!Amount.Value is alway decimal(18, 3)
If The calculation was like sum = 10 + 10 the result becomes 20
if sum = 10 + 2.125 the result becomes 12.125
I want the result to be converted to (18, 3).
so I expect the result in the first example to be 20.000
Your report is correctly returning the values to the necessary precision, it is just only showing the significant figures because you have not told it what number formatting you require and is making a best guess.
If you change your expression to the below, you should get your desired output:
=FORMAT(SUM(IIF(Fields!Type.Value = 0, CDbl(Fields!Amount.Value), CDbl(0.0))),"0.000")

SUM of a SUM in SSRS 2008

I've this report
Here I make the first sum because I've grouped values from each month (months are "Gennaio", "Febbraio", "Marzo" etc etc.). These values are hidden, but anyway I get the sum and I display the sum for each month.
Then I should make the second sum that use values for each month and display the total for each category. Categories are "TOTALE LAVORI RESTAURO", "TOTALE LAVORI EDILE" etc.)
This is the final sum, where I sum values from each category.
Everything is working well, but now I have to add a "month" parameter to the report that returns sums until a selected month. This parameter changes the sum 1 with this expression:
=Sum(IIf(Fields!mese.Value <= Parameters!mese.Value, Fields!costi.Value, 0))
Now, how should I change expression in SUM2 and SUM3 to work with this parameter?
If I copy that code, ther returns #Error and as far as I know I can't use ReportItems sum.
So any suggestion?
SUM #1 could remain Sum(Fields!costi.Value) because you need to display every months.
i.e.: display GIUGNO even if Parameters!mese.Value = 4 (APRILE).
So you have only to change SUM #2 and #3 because TOTALE LAVORI RESTAURO and TOTALI must show only costi from GENNAIO to Parameters!mese.Value; i.e. if Parameters!mese.Value = 4 display only GENNAIO-APRILE even if we have details about GIUGNO.
The expression gave error because you have NULL value in Fields!costi.Value or Fields!mese.Value: convert this value to zero in your DataSet and you won't have problems.

How to make a report with count of type of cases in each month in Acess 2010

I have a database is access with each record having a date and yes/no type columns for each record which shows which category the record comes under. I want to create a report which shows the types of cases in each month by taking a date range as a parameter through prompts. I have done the prompt part but I'm not sure how the query should be to show values for each month in that date range. Can someone please help me with this?
Without knowing the details of your tables, you can Group by the Year and month either as separated columns or with a combined expression like this:
Year(Orders.OrderDate) & '-' & Right('0' & Month(Orders.OrderDate), 2)
If you need more specific help, provide an example of what you have and what you want to accomplish.
Edit:
With the additional info, if i understand correctly you have something like this:
Case Date Threat Stalking Bullying ...
1234 24/12/12 Yes No No
...
And you want something like this:
Date Threats Stalking Bullying
12/12 3 2 10
Then, you can do more/less it like this:
Select Year(Cases.Date) & '/' & Right('0' & Month(Cases.Date), 2) As Date, ThreatQuery.Cases As Threats, StalkingQuery.Cases, ...
From Cases, (Select Count(*) From Cases Where Cases.Threats == 'Yes' And Cases.Date Between #Param And #Param2) ThreatQuery, (Select Count(*)...) StalkingQuery, ...
Where Cases.Date Between #Param And #Param2
Note that this query uses multiple subqueries (one for each type of case), so you may want to be sure that the subqueries are right first, for this, you can just check one, given that all are the same, only change depending of the case's type.
