crystal ball doesnt light up even when programmed fully

I am designing the crystal ball and have this circuit, which is in the attached picture, and FULL PRGRAMMING, and it still doesn't work. What is the problem with this arrangement?

Shouldn't there be a connection from the middle pin of the potmeter going to the 3rd pin of the lcd?
