problem to load pop up on a specific landing page

Hi There, I installed pop up!, my backend is on wordpress 3.9.1 and my shopping cart on woocommerce 2x. I just created a new pop up that have a specific landing page in my store, so the pop up have to appear at a product page. I tried to load it using each options under ''setting'', and the pop up never appear on my dev website, what I'm doing wrong?
