Hi,
Below is the circuit that where I have the cd4017 counters and the Reset switch connected to the GND through a resistor. The issue is it doesn't work on my breadboard unless I remove the Resistor and just short the wire directly to the GND, at that time the Reset switch works!!!
I tried a variety of different resistors ranging between 150 ohm to 1 Million ohm and none of them worked!
Any idea why this happens!

Insert a 100nF capacitor in paralel with the R1 resistor. It will leiminate some noises when you press the reset switch.
