Unable to scroll on website

There are likely a few issues with this code:

1. Unless setup otherwise, theHTML element will be the scrollable element
2. You are attempthing to access a jQuery function on a vanilla javascriptthis
3. You are not actually executing that function to get the value

4. You are not calling the funciton to set the desired value

   $(function() {
       // Change 'body' to 'html'
       $('html').bind('mousewheel', function(event) {
           event.preventDefault();
   
           var $window = $(this); // <--- Wrap the event target with a jQuery object
           var scrollTop = $window.scrollTop(); // <--- Call this function to return the result (use parens)
   
           /*
               Otherwise the reference on this line is to a function, not a value,
               and call the function (instead of setting a property)
           */
           $window.scrollTop(scrollTop + ((event.deltaY * event.deltaFactor) * -1));
       });
   });
