Restrict the phone number to be 10 digit

[deepik_a]

I’m not able to restrict the phone number to be 10 digit in kobo collect app. I have used regex(,‘^[1]{10}$’) but it is not working.
Kindly please help in this.

@deepik_a, you will also need to change the question type to text. This should solve your issue.

Yes i used question type as text even though it is not working.

@deepik_a, where did you put the regex expression?
