Local Number variable

So this is my first time working with Get Local Number variable.

Im close to finishing the mod, but it doesnt quite work yet..

Im making a mod that compresses 64 iron into 7 blocks and 1 iron ingot.

My problem is that it keeps making another block from just 1 iron.

i cant seem to make it work to where it needs

9 items minimum to create the block

Heres my procedure https://prnt.sc/24zzoz5.. really messy, i know lmao

Can someone help me out?
