countProducts() help

Hello everybody!

is it possible, in cart, to count products only from a selected category?

I would like to count products that are in the category X excluding all the others.

The function countProducts() can count all the products in cart...

please help me!

thank you very much

All I want is to add a warning message like this:

"Thanks for adding n.X products from Y category"

nobody can help me writing this ocmod?
