I am following an example from a book. I could not figure out when I submit the first form I get a balnk screen. Is there a way to debug a PHP code. I have been on it for the last three hours with no good result. Please help:

<BODY>
<FORM ACTION="HandleContact.php" METHOD=POST>
First Name<INPUT NAME="FirstName" SIZE="20" TYPE="text">
Last Name<INPUT NAME="LastName" SIZE="20" TYPE="text"><BR>
How Would you prefer to be contacted:
