Hey, X; Actually, it's skipped because it's seen as a page anchor. That's a client-side only thing, and the browser would then be looking for: <a name="CC0000" id="CC0000"></a> Instead, skip the hashmark: <a href="http://www.anyurl.com/?mypar=17&color=CC0000";> ... .... and have it parsed similarly to this: <?php if(strlen($_GET['color']) == 6 && preg_match('/[a-f0-9]{6}/i',trim($_GET['color']))) { // Color is a legitimate HTML hexadecimal color $_GET['color'] = strtoupper($_GET['color']); // Set upper-case } else { // Color is not legit, was not supplied, or this may be a lame hack attempt $_GET['color'] = 'CC0000'; // Force default color } $color = '#'.$_GET['color']; ?> -- </Daniel P.
