Cannot pop modal with from tab

Hey all, just started messing around with Ionic 2. Just ran into an issue…

I’m trying to pop a modal from my second tab. I get the error pictured below. My button press is registered, but errors out. Both modal-page and page2 files are in separate folders within the pages directory. Any tips? Thanks!
