Google Spreadsheet script (if and checkboxes) - google-apps-script

Question

function MyFunction() {
for(x=4;x<=45;x++)
{
var sheet = SpreadsheetApp.getActiveSheet().getRange(x, 7).getValue();
var box = SpreadsheetApp.getActiveSheet().getRange(x, 3).getValue();
var box2 = SpreadsheetApp.getActiveSheet().getRange(x, 4).getValue();
if(box == "TRUE" && box2 == "TRUE")
var sum = sheet+50;
else if(box == "TRUE" && box2 == "FALSE")
var sum = sheet+20;
else if(box == "FALSE" && box2 == "TRUE")
var sum = sheet+30;
else
var sum = sheet;
SpreadsheetApp.getActiveSheet().getRange(x, 16).setValue(sum);
}
}
columns 3 and 4 contain checkBoxes the column 7 contain integer values, the idea is to add +50 if both checkBoxes on its row are checked, +20 if only the first one is checked, +30 if the second one is checked and keep the integer column value if none is checked.

Answer 1

You want to retrieve the values from the columns "C", "D" and "G".
The columns "C" and "D" are the checkboxes.
The column "G" is the numbers.
You want to achieve the following conditions.
When the columns "C" and "D" are true and true, you want to add 50 to the value of column "G".
When the columns "C" and "D" are true and false, you want to add 20 to the value of column "G".
When the columns "C" and "D" are false and true, you want to add 30 to the value of column "G".
When the columns "C" and "D" are false and false, you want to use the value of column "G".
You want to put the result values to the column "P".
You want to achieve this using Google Apps Script.
Your issue is that sum is always sheet which is the value of the column "G".
If my understanding is correct, how about this answer? Please think of this as just one of several possible answers.
Pattern 1:
In this pattern, your script is modified.
Modification point:
When the value from a checkbox is retrieved with getValue(), the value is the boolean type. In your script, the string values of TRUE and FALSE are used at the if statement. By this, var sum = sheet; is always run. I think that this is the reason of your issue.
Modified script:
When your script is modified, please modify as follows.
From:
if(box == "TRUE" && box2 == "TRUE")
var sum = sheet+50;
else if(box == "TRUE" && box2 == "FALSE")
var sum = sheet+20;
else if(box == "FALSE" && box2 == "TRUE")
var sum = sheet+30;
else
var sum = sheet;
To:
var sum = sheet;
if(box === true && box2 === true)
sum = sheet+50;
else if(box === true && box2 === false)
sum = sheet+20;
else if(box === false && box2 === true)
sum = sheet+30;
Note:
At Google Apps Script, even when the variable of sum is declared in the if statement, sum can be retrieved at the outside of the if statement. So the script works. But from the scope of variable, I recommend to declare the variable of sum at the out of the if statement like above modified script.
Pattern 2:
In this pattern, your goal is achieved by reducing the process cost from your script. In this case, the values from the columns "C" to "G" are retrieved with getValues(), and the retrieved values are processed. Then, the result values are put to the column "P" with setValues(). In your situation, when getValues(), setValues() and map() are used instead of getValue(), setValue() and the for loop, the process cost can be reduced. Ref1, Ref2
Modified script:
function myFunction() {
var sheet = SpreadsheetApp.getActiveSheet();
var values = sheet.getRange("C4:G45").getValues();
var numbers = values.map(function([c, d,,,g]) {return [
(c === true && d === true) ? g + 50 :
(c === true && d === false) ? g + 20 :
(c === false && d === true) ? g + 30 : g
]});
sheet.getRange(4, 16, numbers.length, 1).setValues(numbers);
}
