Motors to H-Bridge Problem

I know the problem isn't my H-Bridge, because when I physically put the bridge logic to HIGH and LOW, then the motors spin in a certain direction and when I reverse to LOW and HIGH the motors spin in the opposite direction (as it's suppose to). The problem is in the ATmega328 isn't sending the signal as I would expect and want to know if it's a coding error.

Thanks, though. I shall attempt to throw a schematic up there, too.

Oh, the H-Bridge is purchased and is the L298.
