Why won't LENGTH(FieldName) validate at field exit?
I am wanting to validate a field called ISBN10 that guarantees that a field is exactly 10 characters. My calculation validates just fine, but only when committing the record. On the other hand, a validation of a minimum # of characters validates when leaving the field. Why is that? There doesn't seem to be that much difference. I really need LENGTH validation to work on field exit. Am I resigned to a trigger?
Thanks for any help!
