How to choose a specific layer？

var layerIndex = fl.getDocumentDOM().getTimeline().findLayerIndex("your_layer_name");

fl.getDocumentDOM().getTimeline().setSelectedLayers(layerIndex[0], true); 

/* if you have same named layers, index 0 might not be what you want. */

Still not working

the code i suggested works.  if you have an error it's elsewhere.

if you want me to download your file and fix those error(s), you'll need to tell me what you want the code to do and you'll need to hire me.  ie, i generally don't download and correct errors unless i'm paid.

free help i offer via the adobe forums.

You can open my project file and test it

an.getDocumentDOM().enterEditMode('inPlace');                                                          

var layerIndex = fl.getDocumentDOM().getTimeline().findLayerIndex("layer_3");

an.getDocumentDOM().getTimeline().setSelectedLayers(layerIndex[0], true); 

an.getDocumentDOM().setElementProperty('firstFrame', 5-1);                                          

an.getDocumentDOM().exitEditMode();
