avoiding whitespace in inputs

hello world.

i have several user inputs throughout my script.  sometimes people copy and paste entries into these inputs and dont realize they have a space there - so their results are wrong.

i know i can use stringstripws to every input entry, but is there a cleaner way of doing it?  i checkedd the input styles and extended styles to see if there was anything i could specify that just wouldnt allow a whitespace character for that input but none of them seem to do that.

anyone else come across this?

thanks in advance.
