you will need to edit this line:
$WA_redirectURL = "tbl_contacts_Results.php";
to pass the querystring session and the recordnumber:
$WA_redirectURL = "tbl_contacts_Results.php".$_SESSION["QueryString"]."#".$row_WADAitems['ItemID']."";
the code for the record number will be different for your page, it will be the same variable used to pass the record number to the update behavior.
