rmx traktor pro 2 and jog wheels

hi, i recently got a rmx and ive been using it with traktor pro 2.0. everything seems to work fine except the jog wheels. they dont do anything to the song. i can browse my folders and files with them so i know they work, but i cant scratch or scroll through the song with it. would that be a problem with my mapping? im using the one hercules provides so i figured that would be the default setting for them. if i were to map it on my own, what function would it be? i attempted to map everything out, but it was futile. any advice would be greatly appreciate. thanks
