I was too busy when you posted that, but I didn't understand why a very 
simple script doesn't work for this.  I use this in a field script if I 
want to restrict it to numeric input:

on keydown whichKey
   if whichKey is a number then
     pass keyDown
   end if
end keydown

It works fine.  What was the point of that long winded thing?
