Re: How can a field be formatted to limit the specific characters it accepts.

This works but I had to remove the returns so the script was one continuous line. And I had to add an xtra } at the end

The simpleist:

event.rc = event.value == "" |event.value == "M" || event.value == "Q" || event.value == "X"; or a validation with a prompt: if (event.value !="") {if( event.value != "" && event.value != "M" && event.value != "Q" && event.value != "X" ) {app.alert("Input must be M, Q, or X", 2, 0);event.rc = false;}}

Thanks
