…and here is the expression itself, for those (like me) who want to see these things through to the conclusion…

Where “Scaled” is the name of the layer that is becoming deeper in the Y axis.
The expression is applied to the Position value of the layer that’s getting out of its way.

I love math. I just don’t understand it.

Thanks again Dan.

value + [0,(thisComp.layer("Scaled").scale[1]-100)*(thisComp.layer("Scaled").height-thisComp.layer("Scaled").anchorPoint[1])/100];

Mr Ebberts.

You must live and breathe the logic of this… Wish I had those skills.
I am humbled by your rapid — and 100% successful — solution.

Thank you.
