Hello All. Been playing around with some linked dropdowns.

Not a PHP genius, so maybe it has something to do with that..? Thanks in advance! An answer ASAP would be most greatly appreciated! [B]contact.php[/B] [CODE] <form method="post" action="contactengine.php"> <table> <tr> <td class="left"><label for="Name">Name:</label></td> <td><input type="text" name="Name" /></td> </tr> <tr> <td class="left"><label for="State">State:</label></td> <td><select name="State" size="1"> <option value="AL">Alabama</option> <option value="AK">Alaska</option> <option value="AZ">Arizona</option> <option value="AR">Arkansas</option> <option value="CA">California</option> <option value="CO">Colorado</option> <option value="CT">Connecticut</option> <option value="DE">Delaware</option> …
