Can't get 74LS590 to work

Question

I'm currently trying to count the pulses from a 555 timer. I've opted to use a 74LS590 (8-bit binary counter with output register; 3-state).

However, I can't get the counter to count anything. I've checked on the datasheet and I think I wired everything right. Am I missing something ?

Thank you.

I'll know it for the next time, thank you for the information. — David Kolar, Feb 09 '20 at 21:53
i just have to give you an upvote for the effort that you made to provide a clearest possible picture of your circuit ... even though it is not a schematic diagram, it is a pleasure to look at — jsotola, Feb 09 '20 at 22:03

Wire pin 13 to pin 11 instead of VCC that will clock the count through output register. The output will be 1 count behind what is in the counter.
