getting symbol to play animation in symbol

I'm creating a interactive project. I trying to get a symbol to play a animation that inside of a symbol. Does anyone know what script i should use.

I tried:

sym.getComposition().getStage().getSymbol("frame1").play("rev");

This didn't work and now I'm stuck. I pretty much want the button/symbol to trigger a animation that is in symbol which will be a transition to the next page.

I can load files if it will help just let me know.

Im using Edge animate 2015

Thanks
