What Could Be Preventing My 7 Segment Circuit from Running in Multisim?

[tqcenter2002]

Hi All,
I'm a student and I work with Multisim - I want to create a Simple 7 segment circuit using the Multisim
I have created the circuit step by step looking at a circuit in a datasheet of the 7 segment - and it didn't run at all. Why? (see picture attached)

Can someone help me with that please?
Any help would be appreciated.

Thanks in advance,

U2 - common anode or kathode?

In your simulation, when you sequence the switches, what output voltages do you get from the IC?
