Finding some calculation

How can add a question if the amount is not equal so the question should show error message like it’s oposite (Total number ${total} = ${totalh})

How to validate the female and male entries with the total entry

Hi @Sylvain_DOAMBA, Simply expanding what @stephanealoo has advised. In the survey tab of your xlsform: [Image 1] Data entry screen as seen in Enketo: (wrong entry) [Image 2] Data entry screen as seen in Enketo: (wrong entry) [Image 3] Data entry screen as seen in Enketo: (correct entry) [Image 4] Reference xlsform: Calculation.xlsx (9.1 KB) Have a great day!

Basically you can create a note type question, which set to required = TRUE if certain criteria (which is your calculation) doesn’t fit.

If you need further help, don’t hesitate to ask for more

How can compare the two if the are not equal it should give us the error msg , like, i have a total of student in first question and we sum female and male , so we show it in a note question and we add one more note question to compare total of student and the sum of that?
