Hi Dan, you are our guru, thank you.
I wanted to consult you:
I want to be able to modify with a slider controller the size of X and Y separately. But I have an animation made in X.

I hope you have explained me well.
Thanks you!

x2 = thisComp.layer("Nulo 8").effect("ancho tweet")("Deslizador");
x = linear(time,key(1).time,key(2).time,key(1).value[0],x2);
[x,value[1]]
