I'm trying to make this circuit for my final project and I'm not sure what I'm doing wrong.
This is what it's supposed to look likecircuit 2.PNG
This is what I have so far.circuit.PNG
Thanks

A voting system is a system that can be used to simultaneously provide the number of “yes” votes and the number of “no” votes on a subject of interest to a group of audience. In this project, the system includes a switch for “yes” or “no” selection at eachposition in the assembly and a digital display for the number of yes votes and one for the number of no votes. Each full-adder can produce the sum of up to three votes. The sum and output carry of each full-adderthen goes to the two lower-order inputs of a parallel binary adder. The two higher-order inputs of the parallel adder are connected to ground(0) because there is never a case where the binary input exceeds 0011 (decimal 3). For this basic 6 -position system, the outputs of the parallel adder go to a BCD-to-7-segment decoder that drives the 7-segment display.The resistors from the inputs of each full-adder to ground assure that each input is LOW when the switch is in the neutral position. When a switch is moved to the “yes” or to the “no” position, a HIGH level (VCC) is applied to the associated full adder input.

If this was how the problem was presented to you, find a better school.

Look at those resistors from the full-adder. Where do they go to ground to assure a LOW?
