Putting Image Slider on Right of Homepage

[TillyOak]

Hi guys, I was attempting to put the image slider on the right hand side of the homepage using this topic:

https://www.prestashop.com/forums/topic/450576-how-to-put-the-home-slider-on-the-right-side-of-the-homepage/

The full instructions are as follows:

You need to add a hook to the homeslider.php so it hooks in the Home Tabs.

Make a space around line 604 and add the code below, 
 
 public function hookDisplayHomeTab($params)
     {
      return $this->hookdisplayTopColumn($params);
 
     }
 
then transplant to Image slider for your homepage to displayHomeTab (Home Page Tabs)
Now go to displayHomeTab in Modules, Positions and move the Image Slider to top of list
Now go to displayTopColumn and unhook Image slider 
Your Image Slider will now be in the Center column above the Home tabs

and I get as far as transplanting the image slider to "displayHomeTab" which is apparently "successful" but then when I go to displayHomeTab to move the image slider to the top of the list it doesn't appear in that column at all - it says it transplanted it successfully but it just doesn't show in "displayHomeTab".    Any ideas?

Thank in advance
