[SOLVED] My Custom Utility Block Isn't Working

[This has been solved already!]

Alright, so I attempted to make a custom utility block.

Already made the textures, all I had to do was make the procedures and the GUI.

So I made 2 procedures and 1 GUI. But it isn't actually working.

EnergyForgeProcedure:

• Added the procedure on my utility block's "On block right clicked" trigger.

EnergyForgeSlotHandler:

• Added the procedure on my utility block GUI's "Item taken from slot" trigger.

When I run the client on MCreator and placed specific items on Slots 1 & 2 of the GUI, nothing happens.

I don't know why it isn't working, please help. Thanks!
