My javasript file is not working : My javasript file is not working. I can't see it in the inspector. I think it doesn't loaded at all.

There is missing something in my file?

This is my whole js file:


    $(".sf-main-menu li").click(function() {
    
      var whatTab = $(this).index();
  
      var howFar = 160 * whatTab;
    
      $(".slider").css({
        left: howFar + "px"
      });
    
    
    });

I added it to the .info file.
