Hello. I made ACCOUNTING CODE field in an existing CUSTOM FORM mandatory to fill in. However, even though I designated it as a mandatory field, I am finding a loop hole. The system allows the user to enter letters and/or numbers but I want them to enter in numbers so that they cannot bypass this important field by entering bogus information that defeats the purpose for having the mandatory field such as "See Joe Smith for the code". How do you program that field to require numbers only? Yolanda Rowe
