you will need to hand code the redirect
<?php
if(isset($_POST["Recurring"]) && $_POST["Recurring"] == "1") {
header("Location: kids_insert_shift_recurring.php);
}
?>
in the insert behavior, ther is a section for Save ID In Session As, enter a name for the session variable there, then on the kids_insert_shift_recurring.php use the session to filter the recordset.
