Ooo I see. Thanks Riamus didn't understand that.
By the way mpot, I don't understand how to use the $2 $+. Could you give me an example as to how it would be used in this script?
Also I remember a friend telling me you could put something like $2- and it meant that the script would not run if $2 was empty or not specified. I know I did a if $2 == null thingy. BUt whats the command just for my own curiosty, is it $2-?
