[Solved]Dropdown to display amount of products per page in front end not appearing?

[Accounts]

I have set it to 8 default per page.

In pagination I have altered the code so that:

$nArray = intval(Configuration::get('PS_PRODUCTS_PER_PAGE')) != 8 ? array(intval(Configuration::get('PS_PRODUCTS_PER_PAGE')), 8, 16, 32) : array(8, 16, 32);

Is there something I need to turn on or add in order for this drop down to appear?

Thanks.

Edit: Nevermind, silly me. I just had to add an extra product for it to appear.
