you has an extra "?" character, it should be:
<script language="language="javascript">
WA_setSelectionsInChildList(MM_findObj('User_Update_group_11_Country'),<?php echo $row_SecurityAssistusers['UserCountry']; ?>);
WA_FilterAndPopulateSubList(rsStateList_WAJA,MM_findObj('User_Update_group_11_Country'),MM_findObj('User_Update_group_State'),0,0,false,': ');
WA_setSelectionsInChildList(MM_findObj('User_Update_group_State'),<?php echo $row_SecurityAssistusers['UserState']; ?>);
</script>
the trick to temporaly detach a page from the tempalte is to locate the html tag and the template tag next to it, for example:
<html><!-- InstanceBegin template="/Templates/themed_content.dwt.php" codeOutsideHTMLIsLocked="false" -->
remove the template instance begin tag using an external editor, then make you page changes in dreamweaver, then put the template instance tag back in.
this will not effect the scripts from being removed from the body onload event though.
