Trouble with store product pages

I have created a store grid gallery that features my products, but when I click on the products I am not taken to a product page and I don’t know how to add a link or if there is another step I’m missing. I have created a dynamic product page but can not figure out how to link it to a store grid gallery individual items. Help or tips wanted please!

Have you created the product gallery yourself using a repeater or do you use the existing store’s product gallery?
