Hello,

I am trying to input a question validation equation for a multiple choice question where the other option is a fill in. I'm getting this error though and not sure what I am doing wrong.
 
I want to validate that the number that will be entered will be starting with +31 and after that 9 digits will follow.
 

Thank you.

 

Hi,
1. It is wrong syntax; there are two slashes missing
regexMatch("/^\+31\d{9}$/",Q1_other)

2. The main issue.
The leading "+" is not stored. There are some other threads about this here.
 
As the "+31" is a constant value you may only show it in front of the entry field with
regexMatch("/^\d{9}$/",Q1_other)
 
 

Or you force a "0031"
 

Or you redesign the question and use an inputmask.
