How can I make a limit to the 'integer' data type (e.g. 01 to 99)?

Hi @tanzilhuda,

Backing up with what @bernieseville have said you could do the same as shown in the image below:

In the survey sheet of the xlsform:

Note: With this expression you will not be able to enter 00, hence integer between 01 to 99 are only accepted.

Reference xlsform:

GOOD DAY!
