plugin-nextgen-gallery

I’m using a plugin, NextGEN gallery, to display photos. Each gallery from this plugin corresponds to a different sub-page, so I’m using conditional shortcodes to assign the right gallery to it’s corresponding sub-page.
Problem is, it’s not working. I’ve used this exact setup before without issue, which leads me to believe that whatever is causing the problem now is probably something small I’m overlooking. I think a pair of fresh eyes would help out a lot. Thanks in advance.
