AE expression that turns on a layer only if a certain layer is on?

[Scott Mcgee]

Unless you’re trying to do something else with it.

This should be fine.

if(thisComp.layer(index+1).active == true) 100 else 0;

for cc2019 as I’ve not upgraded. This should work based off what I’ve read.

if(thisComp.layer(index+1).active == true){
100
} else {
0
};

Just realised when testing it, I didn’t write it the other way round.

It wants to be 0 else 100
