Can't get PlayGroup to work right

[lovinglygaslight]

What I've got is

Begin GameMode

If IsControlPressed 0 == 1 
PlayGroup Forward 1
Elseif IsControlPressed 0 == 0 
PlayGroup Idle 1
endif

If IsControlPressed 1 == 1 
PlayGroup Backward 1
Elseif IsControlPressed 1 == 0 
PlayGroup Idle 1
endif

End

Script saves, but the issue is; The Forward animation plays too fast (or maybe not at all?) so the actor zips forward at ludicrous speeds, and the Backward animation doesn't play at all.

 

Any help? I've tried tweaking the SpeedMult AV for the actor to no effect.
