Constraint by sing

Hello,
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

Hello
