So, i am trying to create a circuit using 3 inputs, a,b,c. but the and gate i am trying to use wont accept c as a valid input, i am altering a copy of the tst,cmp, and hdl files in order to get this to work. i built the circuit in logism and got it to work, but converting it to the files offered with the nand2tetris built in chips, i cannot get it to work since the and gate will not accept c as an input.
