Bottom row not working on keyboard

[SchraderMJ11]

I am making good progress on my first keyboard build. But one, hopefully last , issue has me at a stand still. I am unable to get any keypresses from my bottom row. I have a 5x14 layout, but I've only wired up and programed the right 7 columns (I'm building a split keyboard). I've put a multimeter on the bottom rows diodes, and all the way back to the pins. Current flows as expected.

I can only assume I have a software issue. Would anyone be willing to review my code and see if you can tell me what I'm doing wrong?

My code is located here:

Thank you in advance for any help!

I found the problem was a fritzing pin on my arduino, luckily had an extra pin I could use.

How did you figure out it was the Arduino's fault?

The entire row wasn't working so I knew it either had to be my soldering on the Arduino pin or the connected switch, or the software reading that pin, or the pin itself. So I tried resoldering that pin and all other connections and still same issue. So I moved to a different pin, updated software, and it worked.
