Remove Sidebars from an ezpage

[kashyyyk]

I want to remove the left and right sidebars for an ezpage and can't get it to work.

The ezpage id is 17
I also use CEON Uri mapping and the page is called 'Knock-Offs'

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'list_pages_to_skip_all_right_sideboxes_on_here,separated_by_commas,and_no_spaces')) ) {
    $flag_disable_right = true;
  }

I tried it as

// the following IF statement can be duplicated/modified as needed to set additional flags
  if (in_array($current_page_base,explode(",",'Knock-Offs')) ) {
    $flag_disable_right = true;
  }

and it didn't work.

How would I do this?

Thanks
