Is this homework?
it does not even simulate that is my first trouble !You can't directly connect LEDs to the outputs.
They clamp the output voltage to their forward drop.
Why are both output nodes labeled with a (?)?
That circuit will not work properly for the JK logic of both inputs at a logic high.
once one level is low and the other high, we then use a close to give a pulse to change the output state! at each pulse one state is high and the other low !hi,
What are the logic levels on U1 and U2, Hi or Lo and/or are they Toggling in sync with the Clock.?

those sign ?, show the circuit is not simulating, that is the logic indicate, is suppose to be at zero if the circuit is working correctly, even before adding the led, the circuit was not simulating !You can't directly connect LEDs to the outputs.

it does not run in the simulator, just null, no simulating indicationsYou have a latch circuit. When you power it up, what is the state of that latch?
If you don't know, how can the simulator know?
You either need to provide inputs that force it into a known state after start up, or set initial conditions on the simulation to allow the simulator to know how it starts up.
Have you simplified the circuit down until you have something that DOES run?it does not run in the simulator, just null, no simulating indications
