Hi There, I am having trouble with validation on a text field on a form.  I want to prevent the entry of special characters, particularly &, %, $, #.  These characters ruin a URL construction that gets sent out.  When those characters are included, the url won't work.  I tried \w* and it works to an extent.  It certainly prevents the characters, but unfortunately, I need people to be able to enter multiple words.  It is a single line field where they enter their company name.  I know i am jsut missing something in the expression validation, but i am unable to build a solution.  Thanks!
