Hi there.
Hope to get an answer soon
It's all day I am working and using Nicolas and others' tips and everything's going fine.
I'd like to know one thing.
How can I make the ' Continue shopping ' button in the popup ( checkout ) go to a link I want ?
I have a webiste in joomla, one of the links in the menu takes to the a Category List module.
I'd like to get users to continue shopping in other categories...

Thank you in advance,

Carlo

PS :

this is the page which goes to categories list.
It's an ARTICLE, to which I added in main-bottom-a position a category list module :
