Hello guys, I have some trouble to edit custom theme (sp_revo17)

in header.tpl,

Hi,

{hook h='displayCart'} will display the result of the  hookDisplayCart() method of each module hooked on displayCart.
You will be able to find them in design > positions. It should be a module provides by your theme as i don't have any hook called "displayCart" on my PS 1.7.4.2.
