Game works on simulator but not on device...

I have built my first game and it works on the simulator but not on the device. The Start screen loads up but the problem is when I click instructions or start, nothing happens, it just deletes everything but the background. I think it’s maybe because my gameplay is in a lua file called gameplay.lua and my instructions are in instructions.lua

Also, it goes rajjed when I put my device portrait and tries displaying it portrait.
