Subject Reqired fill From Charlie <tm@tc.com> Date Tue, 01 Jun 2021 15:11:22 -0400 Newsgroups dbase.getting-started In a form is there a way to require that all characters are filled out in an string entryfield? For instance I have an entry field that is pictured like this:  99-99   I'd like to require that all four numbers are entered or you would receive a message and the characters would disappear.I tried if len(entryfield) < 5 on change but nothing happens.  Hope I explained this ok.  Appreciate any help.
