How can i create a constraint in my survey form?

I would like to add restriction on the field… which language that KOBO used on writing code
? and how can i add basemap for the Form


Welcome to the community @sara_7500! Would you mind explaining your issue in detail. At the moment your issue seems to be unclear.

for example if i would like to make the entry of the age field between 1-99
and i would like to give the team specific area work within (basemap )

You could use the regex code to make a constraint as discussed in the post discussed previously:

You should be able to learn more about regex through our support article Restricting Text Responses With Regular Expressions.

If the type is integer, you might just use a range constraint, see here
