I am attempting to simulate the 4017 chip in multisim but I am not getting the expected result. I doubt that multisim is incorrectly simulating the chip, so I think that I am probably just hooking it up incorrectly.

As you can see from the picture, I am giving the 4017 a square wave input and everything works except ~Q5-9 doesn't seem to work at all. For some reason, I can't seem to get ~Q5-9 to change from 0 V no matter what I do. According to the doctronics website and the datasheet, this pin should be high when Q0 to Q4 is high... but it never is.
Does anyone know what I am doing incorrectly? Unfortunately I do not have the actual chip to do this in reality.
