Digital clock using Multisim

[Olti]

Hi!

I am working on a school project which is about simulating a digital clock on Multisim. 

I have created a circuit to show hours, minutes and seconds, but it's not working. 

Can someone help me please to find out where is the error? How can I make this circuit work?

The components I am using are: 

VCC 5V

7447N

7490N

7 Segment Com K Orange

74HC32D 2V (OR gate) 

XFG1 function generator

I would really appreciate your help. 

Thank you!

I rewired this and it's your displays. I figured it out by checking voltage levels. Try using SEVEN_SEG_COM_A and whatever color option you choose
