How Do I Wrap This Conditional Array in tpl_main_page.php?

[limelites]

Hi All,

I'm trying to enable left column in just one page... this one:

http://www.limelites.co.uk/index.php...=shopping_cart

In my tpl_main_page.php I have put this:

  if (in_array($current_page_base,explode(",",'shopping_cart_empty')) ) {
  $flag_enable_left = true; 

But it has no effect... what's wrong with my code?? Please??

I can't use just shopping_cart as I don't want left box enabled in main shopping cart page, only the empty cart page :-)
