Hi guys,
I had set a post code field as not mandatory, 4 characters, user editable etc, but when a used goes in and sets it to a null value it errors because the regular expression I used was:
[0-9]
what would I put in the reg exp field that would permit either a null entry OR 4 numerals?
At the moment I have removed the reg exp altogether but that then causes other issues with a script that is expecting 4 digit postcodes as input.
I can't see the way using the guide from prec help;
Best regards,
Will
