Date of follow up visit to date of enrollment

[Priyanka]

Dear Team,

I am working on follow up form. In which I have 2 questions. Date of enrollment of baseline visit and date of enrollment of follow up visit.
I want to put a validation criteria, wherein kobo should not allow me to enter the follow up visit not falling in the range of 25-35 days following date of enrollment.
So for example if my date of enrollment is 7.4.2024 it should allow me to pick dates between 2nd May to 12 May .
