Error on form submission - using pre made form

I am trying to get my form working. I am using my tech tite form, pre made.

I have tried looking through the docs, but thought I would give the PHP experts here a chance to see if they find the problem.

I am getting:

An error occurred while processing the form .

Our staff have been alerted to the error .
We apologize for any inconvenience this error may have caused.


Here is the code:

Any suggestions on what I can do? You can fill out the form but you only need the fields email address and first name. You dont need to fill out the whole thing.

Thanks so much,

Ryan
