Do I put the code on the movie clip?  
How do I make it do what i want?

// bounce easing out  
Math.easeOutBounce = function (t, b, c, d) {  
if ((t/=d) \< (1/2.75)) {  
return c\*(7.5625_t_t) + b;  
} else if (t \< (2/2.75)) {  
return c\*(7.5625\*(t-=(1.5/2.75))_t + .75) + b;  
} else if (t \< (2.5/2.75)) {  
return c_(7.5625\*(t-=(2.25/2.75))_t + .9375) + b;  
} else {  
return c_(7.5625\*(t-=(2.625/2.75))\*t + .984375) + b;  
}  
};
