Problem with calling animation from script

hi, i imported a 3Dstudio model with animations in unity, i split the animations in walk and fight.
i created this script:

var clip : AnimationClip;
function Start(){

i assigned the animation clip as variable in the inspector of the script attached to my model, but i still have an error:
The animation state fight could not be played because it couldn’t be found! Please attach an animation clip with the name ‘fight’ or call this function only for existing animations.
Can someone help me?

Well, are you sure that the AnimationClips are added to the animations array on the Animation component you’re using? You can only play animations which are in this array.
