Robert Penner Easing Equations! How Do I use Them

1

Hey,
I am just wandering how do i use the equations I downloaded from robertpenner.com.

when ever i try even working out of the book i get error messages like

Error Scene=Scene 1, layer=Layer 1, frame=1:Line 350: There is no method with the name ‘easeOutBounce’.
return(Math.easeOutBounce(t * 2 - d, 0, c, d) * 0.500000 + c * 0.500000 + b);

Why does it say there is no method with the name bounceEaseOut

Can someone tell me who i can use these in my flash movies. I tried everything out of his book and i still get it wrong.

Thanks nugget
