Issue description

I created a block that is placed above a jukebox: It has 12 inventory slots that Discs are placed into.
The only trigger I have set is for when redstone is detected OFF as I read that the jukebox creates a redstone signal when it's playing.
The code first checks below it to make sure it's a jukebox.
It is then supposed to generate a random integer and save it to a variable.
That variable is used to select a slot from my box and send it to the jukebox as well as take the item in slot 0 from the jukebox and send it to my block. It loads up fine in the game but crashes as soon as the first disc ends playing. I initially manually place the disc into the jukebox as i don't want to mess with the triggering until I isolate what the problem is with the random number.

General Information on what you have done to fix it: I need the random number so it can select a random disc from the block I created.. so I'm at a loss. I can't find a workaround for the random number.

How to reproduce this issue?

play a disc, when the disc ends the game crashes

Operating system
