Keyboard-related question: Certain keys not working

I recently had to get rid of a keyboard and am using an extra that was lying around. It seems to be working well enough, but none of the “F” keys work (F1, F2, F3, etc). I need a new one anyway, but is this a problem that may be fixable, or just something wrong with the hardware?

EDIT: I seem to have accidentally fixed this. Sooo disregard this, please.
