Ok, I'm slow so please forgive me. I've never heard of a loop variable unless you mean any variables contained within the loop itself not being able to be used outside of the loop unless it's a global variable. Or is $loop a built in variable I haven't heard of before? *sigh* If you find the book of all knowledge please feel free to lend it to me, lol.
