Custom Crafting Table Not functioning

Ok- So, I made a custom crafting table (or tryed to) called a "Nutrient Sequencer."

The craft i made using a procedure hasn't been working.

Basicly, it looks like a crafting table's UI, but with 2 extra slots on each end, with one slot below it for the output, with a total of 13 slots (including output).

Im trying to make it craft 4 of an item when i put 4 resin in a diamond formation (every slot but the middle and edges) in the middle, and paper on the 4 side slots. 

my code isn't working for it though- please help T-T

And be descriptive. I don't know where many blocks are because im a beginner. I'm also having trouble making custom mobs spawn in my custom dimentions.
