right syntax for regex in user extended fields [closed]

Question

I'm trying to add a custom field with a regexp. I have set it up to use

^[A-Z1-9]{5}(-[A-Z1-9]{5}){4}$

which is the format of a windows product key. But no matter what I try I get the error

19 - user_lic - Wrong code...: Empty value

wrong code, is my error message, but what am I doing wrong?

 

Answer 1

Ok, found out. For others that need this, in fact the hint to use delimiters is given. But what actually is meant is that you have to set the regex between quotes. So '^[A-Z1-9]{5}(-[A-Z1-9]{5}){4}$' works in stead of above.
