Soo many things wrong with this circuit: 1: You "connected" a cable on top of the hex display, the input is in bottom and bottom only

2: There are 2 inputs to a wire connecting to the final hex display

3: hex displays display 4 bits, not 8. Split the 8 bits in 2 halfes and connect them seperately

4: C_out output pin is not connected

5: C_in is not connected and pin is an output, not an input

6: Input pins have 1 output and not on any side nor any position
