Problem in virtue mart product list

[Epic Noob]

I`d made virtue mart product list and category for mysite But when i tried to click on products then it was not open and show me the wrong url page but if i click on add to cart button then everything works fine. I ain`t knows what is the problem behind of it.
I`m using virtue mart version 2.0 and joomla version 1.5.26

This was my url:-
