I don't know if I'm doing it right i got 2,173?hi g,
That's great, at least you know the 4026/LED is now working.
Try this, connect the sensor to the input pin #1 of the 4026, measure with a voltmeter the voltage on pin #1 while you move your hand about in front of the sensor, what voltage do you measure.?
