Thanks for helping me, but can you be more specific for me?

In my workspace, I created 10 layers since I don’t know how to write an automatic expression on Opacity, so the opacity of my first ‘Image Choice_1’ layer is 100%, and I wrote this on ‘ImageChoice_2’ layer: ‘ if(thisComp.layer(“ImageChoice_1”).transform.opacity>=100) 50 else 100; ‘.

How to add your expression(index*100 thisComp.layer) to mine?
