Including scrolling text in sliding menu?


I had follow with sucess the tutorial “sliding menu” that I want to use for my website.
Here is the link of the tutorial to see what I’m talking about:

I replace the look of each window of this tutorial (1,2,3,4) to began the pages of my website. Now I try in one of them to include a simple scrolling text.

So I did a tutorial of scrolling text. It work totally fine but NOT when I visualise it from my sliding menu.

Why the scrolling text tutorial work when it is made in the Main Stage but not when is in a movie clip of my sliding menu window?

Any advise or idea, please.
