Scheduled script fails to load Item Record ..

Hi,

I have a Scheduled script that updates certain fields of the Item Record.The script has a search function which search for items.
var searchResultArr = nlapiSearchRecord('item', null, filtersArr, cols);
It succeeds in searching the items..but the script fails when it reaches the line
record = nlapiLoadRecord('item', itemIntId);

Any ideas??

 //for (var i = 0; searchResultArr != null && i < searchResultArr.length  ; i++)    for (var i = 0;  i < 1 ; i++)   {       itemRecord = searchResultArr[i];       manuText = itemRecord.getValue('custitem_manufacturer_text');       deptText = itemRecord.getValue('custitem_system_text');       categoryText = itemRecord.getValue('custitem_category_text');       itemName = itemRecord.getValue('name');       itemIntId  = itemRecord.getValue('internalid');              nlapiSendEmail(-5, '43486', 'Infra :Item before update ',emailMsg, null, null, null);      //load the record            record = nlapiLoadRecord('item', itemIntId);         //set the Department,DNet Manufacturer & DNet Category fields     record.setFieldValue('custitem_manufacturer', manuText);    record.setFieldValue('department', deptText);    record.setFieldValue('custitem_category', categoryText);         nlapiSubmitRecord(record, false);           record = null;          emailMsg = emailMsg + "n" +i +":"+ itemName ;        }
