Please see the comments and questions embedded in this code snippet:

            protected function btnGo_clickHandler(event:MouseEvent):void
            {
                // I fetch a bunch of photo subject records ("items"?) from a back end DB
                getSBJsResult.token = baa_data_svc.getSBJs(edtSrch.text);

                // How do I get the record count (item count) from the object returned above
                // so that I can display it in the tab label in the next line --->
                // Also, Is "+" the correct symbol for contatenation?
                tabSBJs.label = 'Subjects: ' + Whu?

                // Now I grab some photo session records, but I must feed it the unique ID from the FIRST
                // record (item) in the result set retrieved above, how do I get that value (it's a string (GUID))
                getSESsResult.token = baa_data_svc.getSESs( what goes here?  );

                // What every you show me above, I'll use on the line below.  It still
                // contains the dummy param value
                getIMGsResult.token = baa_data_svc.getIMGs('BF3B9F5AC1C7422C8B79C66369EFDFE9');
               
            }

Thanks in advance for any help.
