I tried your script, 
Move your defaults block before your onChange function and that will fix it.
Also, you should wrap your entire Script inside a function block to keep your variables local to your script, and not global.

Hi, your loop is wrong. Selected Layers being an Array starting at index 0,  your loop should be ( i < layerNumber NOT <= ) like so: if (layerNumber >= 1){        for (var i = 0; i < layerNumber; i++)        {           var layerNames = chosenLayers[i].index;           recurse_children(comp.layers[l...

you can loop through the layers to find the one named "Hand". this will return a layer with a specific name, assuming you only have one layer with Hand in the name this is case sensitive. var handLayer = findLayer(app.project.activeItem,"hand") function findLayer(curComp,name){  ...

Hi Mike, You'll have to create new solid for each layer selected. Solid can only be created from a comp layer collection. Because you don't want to screw up your actual comp and loop by creating new layers in it and therefore changing the indexes and layer numbers, you can create a new comp, add a n...

Hi,
Sometimes, I use the comment to store values that I need to retrieve, or to tag layers. It exists inside the project panel for any item. Or on layers in a comp.

app.project.item(index).comment  , it's a string so you could store stringified JSON I guess (never tried it);
