Adding items to a Google Forms list from a spreadsheet range -

i struggling past last line in code appreciated:

the error getting "array empty: values (line 16, file "code")". have double checked item id, spreadsheet id , there data pick within correct range. pointers or insights...?

  function getfleet() {   var ssdefects = spreadsheetapp.getactivespreadsheet().getsheets()[0];   var rngfleet = ssdefects.getdatarange();   var values = rngfleet.getvalues();   var fleetlist = [];  //use column 0 , ignore row 1 (headers)   (var = 1; <= values.length; i++) {     var v = values[i] && values[i][0];     v && values.push(v)   }    // form id & list id   var defectsform = formapp.openbyid('<form key id>');   defectsform.getitembyid(794194842).aslistitem().setchoicevalues(fleetlist); }; 

nothing pushed array fleetlist. coding in loop faulty. assuming want push first column (not including header), try , see if works

function getfleet() { var values = spreadsheetapp.getactivespreadsheet()     .getsheets()[0].getdatarange()     .getvalues(); var fleetlist = [];  //use column 0 , ignore row 1 (headers) (var = 1, len = values.length; < len; i++) {     fleetlist.push(values[i][0]) }  // form id & list id var defectsform = formapp.openbyid('<form key id>'); defectsform.getitembyid(794194842)     .aslistitem()     .setchoicevalues(fleetlist);  };
