animations only paying after trigger released

I have added some animations to go with the flight code for my player model. I am using T3D1.1a.

in default.bind.cs I have

function glideTrigger(%val)
{
   $mvTriggerCount5++;
}

moveMap.bind( keyboard, g, glideTrigger );

model goes into flight position but doesn't play the animation untill after the trigger is released.
all animations play fine in model editor.

the flight mechanics work fine and are designed to be enabled only when trigger is pressed. when trigger is
released it goes into fall state.

EDIT: ok it seems that the animation is trying to play but keeps resetting while the 'g' key is down.
what would be a better way to do this so the animation can cycle as long as the key is pressed and not
keep resetting?
