Can't pass variables to PHP scripts?! Please help.

Here is my situation...I can't seem to get variables to pass from a GET or POST method to a PHP script. To see for yourself go to: http://www.socopc.com/test.php?testvar=hello_world The source of "test.php" is... <html> <? for ($x=0;$x<5;$x++) { echo $x; } ?> <br><? print "testvar=\"".$testvar."\""; ?> <br><br><br><? phpinfo(); ?> </html> And as you will see, I get the error. Warning: Undefined variable: testvar in c:\root\domains\socopc.com\test.php on line 3 testvar="" Indicating that the variable is empty and has not been passed?! I'm running Win2k Server w/ Apache and PHP 4.1.1. If someone could look at that page (included are most of my settings). And help me fix my PHP configuration? Thanks! ~ Travis
