additional tab&scroller not showing

I have a theme that has 3 tabs & scroller / sliders but I want 4 so I added an additional tab and slider/scroller but it’s not showing. I added a scroller-4.php, and added 4 scrollers in the options.php and added the styles for the scroller 4 in .css but there is still no scroller 4 showing in design, you can see here:

I added this code to scroller-4.php:
