Player 2 right input not working

I've tested both ports with 2 AES controllers and they check out fine so I know it is limited to the second player port. I reflowed the pin on the controller port and on the pcb and checked continuity and it came thru fine. Went to hardware test and still no input. Where should I start looking? I don't know where the inputs register. Thank you

Edit: Found a broken trace on the bottom of the board. Must've dragged my soldering iron when I was reflowing the board. All is well again.
