Zencart 1.3.8 and I am using the default three-column layout for site as well as for all the ezpages EXCEPT for one ezpage. The fundraising ezpage, I want to not have the left and right columns.

Where is the PHP code where I would put in an if-condition such as "if page is fundraising, then display only the center column"?

I see file tpl_ezpages_bar_header.php, but I think this is not the right place.
