Please look at the attached circuit and see if you can find anything wrong. The first LED's 1-17 should sequence followed by LED's 18-22 with each one fading off in about 3 seconds, and then starting over after LED 22 fades off. I have breadboarded this, but only hooked up Led,s #18 &19 circuit, so, I hooked up pin 15 (res) of IC2 to pin 7 of IC4. The first 9 do not light and 10-17 only light and sequence when I touch the metal base on my breadboard (crazy huh). I have checked the wiring and have swapped out IC's to no effect.
