the up button is the only button i put in the breadboard to test the circuit , i didn't put for the mean time the down and clear button should i put that already ?? .. i measure 2 volts and when i push the up button it goes down to zero ..

For the counter to work all the components shown on that drawing post # 46, must be connected.
Look at this drawing and measure the voltages marked in blue, inside the blue box, tell me what on each of the 4 pins.
