Regex

Couple of questions regarding regex expressions. Do they have to be applied
to ‘TEXT’ questions or can they also be applied to ‘INTEGER’ type questions

I am using the following epression to limit integers to maximum of 3,
although the expression works on regex check sites it doesn’t limit how
numbers can be input. Any suggestions?

regex(., ‘^[0-9]{1,3}’)

I would try .<4 as a validation condition or .<4 and .>-1

I’m not sure this is the precise syntax. But I think this approach is the
right one.

You can try including string-length(.) < 4 in your expression

This Regular expression regex(., ‘^\d{4}$’) ensures that you only input 4 digits(numbers), you can change it to the length you want e.g to limit to 3 integers use this regex(., ‘^\d{3}$’) or you can use a much longer but easy to understand one regex(., ‘^[0-9][0-9][0-9]$’) which only allows 3 integers. I hope i answered your question, right? If not, rephrase it, i may not have understood it well. cheers
