[Help] Register errors?

Fatal error: Call to undefined function mssql_connect() in C:\xampp\htdocs\register.php on line 31

This is an error I get when I try to put the register in.
I used this script.

<!-- Start Register -->

I have bolded line 31.
The current info that I have put in is correct, I copied/pasted the mssql_server/mssql_user from the Studio its self, and I have entered the correct password.
Yet, it has failed.

Hamachi is what we are using at the moment, and if the webserver matters it's Xampp.

Any Ideas ?

I can see several problems, but i'll start with the main ones. If you have put correct values in the %mssql_server, $mssql_username, AND $mssql_password fields and it still gives you that error, then you have 1 of 2 solutions. Either install PHP and enable mssql on it (i don't know if Xampp comes with it) or enable mssql in the php.ini file (this is only if Xampp already has PHP).
