Trying to help a friend out with his site that someone didn't finish, and came across a problem.

The contact form doesn't seem to send

I'm not sure where the problem is but i have tried to attach all the relevant files (i might of missed something).

I don't even know where to start please help. The email i'm trying to send to at the moment is redpandadesign@gmail.com but that will change to info@pedrovirgil.net once i have it working.
