Got it. Thank you
Now, I need to know what to put in the dynamic list menu dialog box fields. These are set now to the following:
Options from record set: None
Set Value Equal to: <?php (isset($_GET["invalid"])?ValidatedField("userupdate","User_Update_group_11_Country"):"") ?>
Are these correct or do I need to change something? I have uploaded the updated file.
Thank you for your help!
