I solved my problem and in good forum etiquette I'm posting the solution in case anyone else ever has the same problem.The solution is:^[0-9]{2,2}[\\/][0-9]{5,5}$Just another watch out, I had a setting wrong in my Custom Validation. I previously had it set to "Is Equal to". I think when you click in and out of custom valuation, it automatically resets to "Is Equal to". The setting you need is "Matches Regex".Image attached.
Hi ahmedA,Removing spaces didn't fix the problem :(
