How do I program the displayShowDetailScreen into the showPosterScreen? inside of the SimplePoster.brs.
Here is what I have to work with.

Please go through the Developer Guide to get the gist of using the BrightScript debugger to help in walking through the code…
I made some modifications to your sample here to show the next steps to adding the SpringBoard screen.
