Suitelet Item Permission Problem

Hi all,
I'm sure this is probably pretty basic, but I've been scratching my head at it for some time, so if anyone could offer some guidance, I'd be very appreciative.

I've set up a suitelet that runs a search for items on the website. I'll do my filtering and column results later, but for now, I just wanted to test and see if it works:

function getItems(request, response) {   var columns, filters, results, strJson;      columns = new Array();   columns[0] = new nlobjSearchColumn('name');   columns[1] = new nlobjSearchColumn('internalid');      columns[0].setSort();     results = nlapiSearchRecord('item', null, null, columns);      var callBackFuncStr = request.getParameter('callback');      if (callBackFuncStr != null){    results ? strJson = callBackFuncStr+'({"total":' + results.length + ', "results": ' + JSON.stringify(results) + '});'      : strJson = callBackFuncStr+'({"total": 0, "results": null});';    nlapiLogExecution('DEBUG', 'JSONP Offer', strJson);    response.setContentType('JAVASCRIPT');    response.write(strJson);     } else {    response.setContentType('JAVASCRIPT');    results ? response.write('{"total":' + results.length + ', "results": ' + JSON.stringify(results) + '}')       : response.write('{"total": 0, "results": null}');   };  }
