That must be what he was talking about, but I couldn't figure out how. This is actually incredibly easy lol thank you guys for the help!

There helpful thank you!

So I got it done by

Network storage went into those 2 arithmetics via red.
Item1 * 1 -- output to whatever signal (X)
Item2 * 1 -- output to same signal

Both go into a decider view red aswell.
X < 3,000,000 -- output X 1

That goes into the assembler via red wires ...

I'm currently trying to figure out how to set assemblers to only build an item if the contents on the storage network of 2 items total equal together, is less than a certain amount.

I have assemblers set to if the value is over 0, then disable.
