Ok, this time for sure.

You can't remove the offending characters from selection because it's 
already types as integer. So the variable never had a value that contained 
offedning characters. You were going in the right direction, but you have 
to assign to selection the result of stripping out the bad characters, and 
THEN compare selection to see if it's not equal to chselection.

I think this time we got it.

The sequence that showed the problem before was to enter some numbers that 
were interspaced with bad stuff. All that would be left were the numbers 
and then it tested to see if it was in range.
