Help with script --

[t0nedef]

Ok, i wrote this script to help with wpa wireless connections, but for some
reason, it errors out. It says that the ESSID is empty. I've double checked
my syntax, and it looks right to me. *yes, i did double check the syntax for
the read command*

well heres the code:
