Help! Button procedure called but not functioning

Running forge 1.18.2 with MCreator 2022.1 build 19518.

I am making a mod which adds an item which can increase the efficiency of an item by 1 when combined in a special table GUI.

Currently the button "Combine" calls a procedure but the button NEVER WORKS.

The procedure Test1 is just a procedure which prints "Running!" in the chat:

The actual function that will be called after I fix the button is here. I debugged all of the procedure code but would like to make sure nothing is wrong here too.
