Inside of the field script put something like this: on keyDown pKey
put the number of chars of me into sCount if sCount < 3 then if pKey is not in "1234567890" then pass keyDown end if end if end keyDown This should make it so that everytime a key is pressed in that field it counts how many characters it has, if it is less than 3 it checks to see if it is a number or in the allowed list, if so it passes that key. -- View this message in context: http://runtime-revolution.278305.n4.nabble.com/Limiting-data-entry-in-fields-tp3064388p3064535.html Sent from the Revolution - User mailing list archive at Nabble.com. _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
