Can anyone give me any tips on what I can troubleshoot?
No.
Is the circuit running too fast? Too slow? Did it burst into flames? Think about it - do you really believe that "I'm having trouble" is actual information?
However, the construction does need help.
Add a ceramic decoupling capacitor across the power and ground pins of each chip. Keep the leads as short as possible and connect as close as possible. Value can be anything from 0.1 uF to 1.0 uF.
Add an electrolytic capacitor across the two power buses, anything from 10 uF and 100 uF.
Reduce the length of all power and ground jumper wires.
