Buy Button Shortcode not working

I am attempting to create a very simple page, where people can choose specific quotes, sayings, and images to build a photo slideshow. I have set up individual products representing each option. I want one page to display each option, with only a buy button for them to add that option to their cart. I currently have multiple buy buttons on the same page, but they only add the first product listed.

Is there a way to have multiple buy button shortcodes work? Or a better way to achieve this?
