Thank you Conor for your fast reply. It was my stupid mistake that did not let it working, but now it is fine

I have another question
in my categories I have many pages and in the second and next pages, the url has an end like this http://www.mysite.com/dresses?&sort=20a&page=2, is it possible to get rid of ?&sort=20a&page=2 and just have dresses/p2 or something like that?

Thank You!!!
Love your add on!!!!
