Hi Lince,

You can find a simple but effective script in this old
post that I dug up from the archive :
<http://lists.runrev.com/pipermail/use-revolution/2003-September/022446.html>

However, it doesn't handle what comes into the field
through copy+paste or drag-and-drop. You should be
able to fix that with the following additional piece
of script :
--
local sBeforePaste

on pasteKey
  put the text of me into sBeforePaste
  if "checkAfterPaste" is not in the pendingMessages \
  then send "checkAfterPaste" to me in 5 milliseconds
  pass pasteKey
end pasteKey

on dragDrop
  put the text of me into sBeforePaste
  if "checkAfterPaste" is not in the pendingMessages \
  then send "checkAfterPaste" to me in 5 milliseconds
  pass dragDrop
end dragDrop

on checkAfterPaste
  if the text of me is not a number then
    beep
    put sBeforePaste into me
  end if
end checkAfterPaste
--

You may have to tinker a few bits here and there to
make it work for you, but I hope this get you closer
to a solution.
