Yes!=20
 
It has 2 keyframes - 0 and then100 with the decay expression:
 
amp =3D=20 .03;
freq =3D=20 3.0;
decay =3D=20 7;
n =3D=20 0;

That=92s good = Dan but the=20 Layer B isn=92t decaying properly because it needs to go below 100 for=20= that.

I was thinking of making it time based but I=92d still be = in the=20 same boat.

Happy Monday,

I have layer A that is = scaling from 0=20 to 100  - and then has a nice decay thanks to an expression = from=20 Dan.

I have layer B that I=92d like to be synced up with = layer A (going=20 past 100 and then have the decay) - however layer be is already on = the=20 screen and I only want to the scale past 100 and then bak to 100 = with the=20 decay.

What would you suggest dear kind=20 list?

Thanks,
Rachel
