Constraint by sing

I need help.
In xls form how to do so that the date of circumcision does not precede the date of birth in xls form? What to put in constraint?

Hello @bilal718, You could get quicker response if you share your xls file.

in the constraint column put .>= ${date_of_birth}
you will need to replace date_of_birth with whatever you called the date of birth question in the name field. its best if you add an explanation in the constraint_message column if possible as well

Thanks for the rapide answer.In my xls form, i replace date_of_birth by date_nais by doing .>= ${date_of_birth} in the colomn constraint at the line 291 but it doesn't work. ![SCREAN|690x251]


Hi Bilal,

Sorry your image doesnt show, you may need to attach the excel for us to understand if you havent already resolved the issue.
