Validating field contents in a portal

[Rich]

(I'm sure this has been covered before but nothing came up in my search criteria)

I have a Year (number) field in a portal where I want to force the entry/recording of four-digit years but no matter what validation criteria I set for in the field definition, it won't fault to produce a validation error message if a non-four-digit number is entered, even with a script trigger using a Commit Record script step.

 

What am I missing to get the validation to work? Thanks in advance for your help.

I believe that a script overrides a field validation
