PHP mail Help

Hello all and thanks in advance, I am attempting to get a PHP mail form to work “send a URL” I must be missing something. I a trying to do something like this page http://www.willowcreek.org/events/evite.asp?ID=6 they are using a third party company looks like SQL back end. So I found http://www.ibdjohn.com/sendurl/ and thought that could work pointed to the event page. I have been trying to test it and I have to be missing something, as you can tell this coding stuff is new to me. Here is the test site http://www.fixyourdns.com/html/mail_test.html
