I need help with an script

Well seems like most of the script is working but the contact us page. I guess that would be the email.php. I think the code needs to repair but I have no clue how lol. Sorry i'm kind of new at this. I going to try to take classes on php at the local college. I have tried everything to repair to no prevail but i will post the email.php script to see what you guys think does it need to be repair and how to repair it here's the script.
