Tanktalus, Thanks for your reply. I do appreciate the help. I am very green to perl and "perl speak". The reason I am validating an environment variable is the fact that the value could be passed through the url (if someone happened to guess the variable name). From everything I read, it is suggested that "security through obscurity" is wrong. I just want to make sure that my script will be as "bullet proof" as possible. As for the CGI::remote_host(), I'll have to look into that.

My script was basically pieced together from other scripts I had found. I tried the best I could to understand what was going on and thus the reason for the incorrect use of "return".

I think I understand what you are saying, and I will give this a try.
