        $("#submitmefts").mouseup(function ()                     {                          for(var i=0; i<updateformid.selectedsched.length; i++)                          {                   if(updateformid.selectedsched[i].checked == true)                               {                                  var holdcreationdate = $('#modifycreationdate[i]').val();                                 var holdschedule = $('#modifyschedulenumber[i]').val();                                 alert("the checked button clicked");                    }                                else                               {                                   alert("the checked button not clicked") ;                               }                           }                      });   

i have selected check working getting error trying use 'modifycreationdate' field. putting '[i]' @ end invalid. proper way pull correct index of field?

i know servlet call had similar modifystatus field create different "names" each row wondering if there better/cleaner option.

thanks again
