Basic Bash Help?

[ezb]

I'm new to bash, only been doing it a day or so, but having some trouble with one thing. I am trying to create a script that checks for updates, places them into a file, slightly formats them, then emails them. It's the latter I'm having trouble with, I have copied an email tutorial and doesnt want to work. Here is my code, I know its not the most efficent but it's actuly the first script I've done. sure it's something simple that I cant see but hoping someone else would know

#!/bin/bash
vzupdate -m batch list > maybe.txt
grep 3 maybe.txt > maybe2.txt
 
subject="subject"
email="[e-mail]"
emailmessage="maybe2.txt"
echo"email:">$emailmessage
 
/bin/mail -s "$subject" "$email"<$emailmessage

Any help would be great, cheers
