Query string on windows 2000

Having a problem pulling out the value from the query string on a win2k hosted site.

A basic:

if ($bob) {
print("bob!");
} else {
print("<a href='test.php?bob=yes'>goto bob</a>");
}

works on a linux host, but not 2k I get:
Warning: Undefined variable: bob in c:\webserver\development\test.php on line 3

Anything around the problem? I've searched but couldn't fine anything that helps.

Use $_GET['bob'] instead of $bob. If that doesn't work (i.e. earlier version of PHP, but this doesn't sound like it) use $HTTP_GET_VARS['bob']

For performance and security reasons register_globals has been turned off, and for debugging purposes Warnings have been turned on.

Thanks m8, Whats the syntax exactly? I'm only a newbie and can't get it work.

if ($_GET['bob']) {

Note that that won't work in the older versions of PHP (they use $HTTP_GET_VARS['bob'] instead).

no joy still get:
Warning: Undefined index: bob in C:\webserver\development\test.php on line 4
