Custom crafting table doesn't give an output

I have followed this tutorial:

I've tried replicating the 3x3 custom table for my mod (i have checked multiple times for my mistakes and even imported the procedures in my project) and it doesn't seem to give an output.

I tested the tutorials project and i is working there.

My procedures are litteraly replicated from the tutorial and it doesn't work.

This is a bit urgent because i'm trying to move on to other things, but for them i need to fix this.

(Other forum topics about this tutorial did not help)
