Need help bringing up Details screen

I have made a grid layout for my homescreen, it work fine I still have some xml files to create, however, each row is a different Show, and the posters in the rows are different episodes of that said show. I can't get past the home screen however, i'm completely new to brightscript and I am a little lost at this point. If you could guide me in the right direction to move to the details screen and then the video screen I would be very thankful. I will post the content of my SimpleGrid.brs and my appDetailScreen.brs files.
