Need help with a php function please!!!

Hello i need help with this function, what i am trying to do, is in this form, when people submit this form to go to the next page, i need to take them to the 2nd page, and the information that the person put in the form, to be emailed to me.

This is what i have : how come when i submit it does not send’s the email to me?? what am i missing? should the function be in the section? or where?

At the bottom i have the PHP function for email send.
