I'm really struggling trying to grasp the concept of reg ex rfeplacement. I have been through the documentation and a few tutorials but I can't find something that shows me exactly how to return a string that contains nothing but alpha numeric characters, while stripping out all other characters. Couls someone please show me how to do this? Thanks, Ron
