Renaming layers as part of a script

Hi! I am currently working on a rather large script(for me atleast) to add a couple of effects to a source clip. One of those effects requires me to duplicate the layer 3 times, and I wish to rename those layers as well.

I have tried this code but .name does not seem to work for me:
var footage = app.project.activeItem.layer("Footage");

//RBG Split
var channels = ["red", "blue","green"];
var myLayer = footage;
var myName =;
var newLayer;

for (var i = 0; i < channels.length; i++){
newLayer = myLayer.duplicate() = myName.substr(0,myLayer.length-3) + channels[i];

the script goes through just fine, creates 3 duplicates but does not rename anything.

Any suggestions to what could fix the issue?

EDIT: I just realized that you can swap between Source Name and Layer name in the Layer Editor. I've gotten it to work fine now.

This works. Make sure you're looking at layer names, not source names, in the timeline. Click the the Layer name / Source name column header in the timeline panel to toggle.

As an aside, "myName.substr(0,myLayer.length-3)" probably contains an error, as you're asking for the length of the myLayer layer object. Perhaps you mean for that to be
