Asrarahmed -
 From what I remember (PMW is just an extension of TKinter so this 
should apply here)
it's a lot easier to validate the input when you're using it instead of 
trying to restrict their input.
I.E. when they hit 'submit' give them a little warning saying 'sorry, 
you can't submit unless you have an integer in field "fieldname" .....'
That's most likely the easiest way to do this.
If you just google for tkinter validate entry  you should come up with 
the other way, IIRC (where they can't input incorrect values).
HTH,
