How to move layers into group.

Question

Hi.
I want to make group and input it's name and get layers into it.
var doc = app.activeDocument;
var layers2 = doc.layers;
var txt = prompt("Input layer group name :");
var layerSetRef = doc.layerSets.add();
layerSetRef.name = txt;
for(var i = 0; i < layers2.length; i++) {
layers2[i].move(layerSetRef, ElementPlacement.PLACEATEND);
Can you tell me why this code shows error?
Indicator shows "layers2[i].move(layerSetRef, ElementPlacement.PLACEATEND);" is not right.

I see two main problems with your code.
One is that the enum should be ElementPlacement.INSIDE when moving an artLayer into a layerSet.
The second problem is moving layers changes the index so you can not loop using the index.
Try something like this:
var doc = app.activeDocument;
var txt = prompt("Input layer group name :");
var layerSetRef = doc.layerSets.add();
layerSetRef.name = txt;
while(doc.artLayers.length > Number(doc.layers[doc.layers.length-1].isBackgroundLayer) ) {
    if(!doc.artLayers[0].allLocked || !doc.artLayers[0].positionLocked ){
        doc.artLayers[0].move(layerSetRef, ElementPlacement.INSIDE);
That should move all the top level artLayers into the layerSet. It will skip locked layers and the background layer. You could change the layer locking test to change those properties if you want to move locked layers. To move the background layer you will need to convert it to a normal artLayer before moving.
