Is there a way for me to "trace" or "echo" the value of a variable as an expression is running. I don't even know what this would be called, so searching has been difficult. I came across a post here that mentions alert(text:String), but I think it only works in scripts and not i...

Thanks for the tip! I'll try to break it up more often Your code clears up my problem perfectly!

I'm just wondering why this works:

thisComp.layer("m").position.valueAtTime(time - .1)

but this doesn't:

[position[0], thisComp.layer("m").position[1].valueAtTime (time - 0.1)]

TIA!
