+This Catalog Client Script is used with a Script Include and reference qualifier similar to
+javascript: 'disable=false' + session.getClientData('selected_dept');
+
+The scenario is a MRVS with a reference variable to the customer account table.  When an (active) account is selected in the first row, subsequent rows should only be able to select active accounts in the same department as the first account.
+
+This Catalog Client Script will pass the first selected account (if there is one) to a Script Include each time a MRVS row is added or edited.
