Try this one (script of the field): on keydown whichKey if whichKey is among the chars of "01234567890.-" then put me into tTemp put word 2 of the selectedChunk into sChar put word 4 of the selectedChunk into eChar if eChar > sChar then -- some text is selected delete char sChar to eChar of tTemp end if put whichKey after char eChar of tTemp if isNumber(tTemp) then pass keyDown end if end keyDown Basically it checks to see if the end product would end up with a numeric value, and if so, it will allow the keystroke to happen. BTW: There was no reason to trap for backspace/delete as there isn't a way AFAIK to remove some or part of a number and have the end result *not* be a number.
