Calling a saved search

I want to call a saved search and display the results in a list.

In the code below I've created a list, added the same columns that are returned in the saved search results. However, I get an unknown error. Can someone tell me what is wrong with the following code?

 function demoList(request, response) {       var list = nlapiCreateList('DC - CI Inactive Churches');        list.setStyle(request.getParameter('style'));         var column = list.addColumn('internalid', 'text', 'Internal ID', 'LEFT');      column.setURL(nlapiResolveURL('RECORD','customer'));    column.addParamToURL('id','internalid', true);         list.addColumn('entityid','text', 'Customer ID', 'LEFT');    list.addColumn('companyname','text', 'Church Name', 'LEFT');    list.addColumn('url','text', 'Web Address', 'LEFT');    list.addColumn('phone','text', 'Phone', 'LEFT');        var searchResults = nlapiSearchRecord('customer', 'customsearch_dc_ci_inactive_churches');         list.addRows( searchResults );      response.writePage( list );  }
