Getting result values off of a search resultset, getValue method fails

EDIT:
Problem gone. In my saved search there were a couple of lines where these 2 custom fields were empty, which resulted in every line of that column being empty when I tried to retrieve it through code, once I filtered away these in the saved search, the problem was gone and I retrieved values as intended.

Sorry for the both vague and redundant topic title but that's the best way I can describe the problem in 1 sentence.

I am currently running a saved searched through code.

         var savedSearch = 'customsearch602'; // id-string          var mySearch = search.load({              id: savedSearch          });          var resultset = mySearch.run();          var results = resultset.getRange({              start: 0,              end: 1000          }); // resultset returned as an array
