Another quick question for you smart people:

I am trying to have my upsell section do something different:
If the client has already "added to cart" the main product, when he clicks on the upsell item, the new page gets loaded on the same window.
If however, the client has not "added to cart" the main product, when he clicke on the upsell item, the new page gets loaded on a new window.

Any ideas?

Thanks!
