Doubt abt Sequence vs Scene

For the above example to create a listbox, I have created four layers as said, but I could not get the output ( I am getting only the listbox and not the corresponding text when the list item is selected).

I found that the author of the above example is using Sequence where as I used Scene. I am trying to create a sequence instead of a scene but I could not do that… Kindly tell me how I can open the sequence instead of scene.

I think you guys got my problem

Thanks for any replies…
