problems with animations in a seat

I've been trying to get this script to use a sit animation inside it with no success. I know that its something simple that I'm not seeing.
Its in a little vehicle, I have an animation in the seat, when I sit I'm trying to use that animation. But for some reason its not working. I'm not very good with these large scripts.
Can somebody please help me?

rotation sit_rot;
key pilot;
integer power;
integer listenindex;
string animation; //part of animation
vector position = <-0.25, 0.25, 0.3>;//part of animation


default
{
    state_entry()
    {
         animation = llGetInventoryName(INVENTORY_ANIMATION, 0);//part of animation

        llSetStatus(STATUS_PHYSICS, FALSE);

I don't see where you are setting any animations in that script.

But you will need to stop the sit animation before setting your own.

Darn it, your right. I forgot that part. *blushes a bright red
I'm going to try it now. (works perfect. * blushes even brighter than before)
Thank you Thraxis
