I need to debug this function. It is saying CANNTO READ PROPERTIES OF NULL(reading zero)

 

 

 

 

 

 

function clicked() {

     
var search = document.getElementById("search");
var results = localStorage.getItem(search);

if(results = null)
 {
  document.getElementById("results").innerHTML = "There are no results for that route name."
 }
 else
 {
 
           var stops = results;
  var output='';

  for(var key in stops[0])
  {
               //5
   var output = output + '' + key + ' : ' + stops[0][key] + '
';
  }
  document.getElementById("result").innerHTML = output;
 }

};
