Help please *** PHP4 not installed correctly

Hi I had to move 2 sites from a unix server to a microsoft server and the new ISP was suppose to install PHP4. In a simple php script, http://www.tukulu.co.za (in the contact section after send the form) I get the error message Notice: Undefined variable: Name in D:\Web\tukulu\www\Alpha\MailRequest.php on line 35 Notice: Undefined variable: FirstName in D:\Web\tukulu\www\Alpha\MailRequest.php on line 36 ... which let me guess that PHP is not installed, or at least not correctly. The script was working fine on the unix server. How can I check what is wrong and ask the ISP to correct the problem? Please copy your reply to Paul@gondwanastudio.com. Thanks. -- Kind regards, Paul.
