Move inserter if items on belt > 2 ???

[Zonk]

Hey i have many small loops where ressources keeps cycling forever like say green circuits. Thoose loops are filled by a single Belt and factorys only take items to a extend.

Now i want to connect a belt with a inserter and make a condition like " green circuit (on belt) > 2" so the inserter only starts putting items in a chest if my chosen belt piece have more than 2 circuits.

But i cant get it to work... Someone already did that ? Or have a clue?

Connect belt with inserter. Set in belt to read content witch hold option. In inserter set Enable/Disable and condition "wanted item" > 2. Also set read content in inserter.
