Help with Block Displays bugging out the game..

So I create custom Origins for the Origins mod and I tried to combine a power that I made with block displays..
The power by itself works fine but whenever I add the custom block display function, it all falls apart and Minecraft stops working correctly..
The block display also works somewhat correctly by itself, when I enter it in chat using /function..
I'll send the power and all the functions the block display uses..
Any help is appreciated!
