Hi everyone and thx for your attention.
I’m workin on a little site and i had follow this tutorial about transition for dynamic files on kirupa (transition for dynamic files).
This is the link at the site i’m doing :
And that is the question :
How can i do to have the transition animation closed in the start of the site and then decide to open it clicking on the 4 buttons i got?
I don’t want to see it open immediately but only when i’ll click on the buttons.
I’ve searched inside the forum but i didn’t found what i’d like to want, also i’m an actionscript rookie… 
Can you help me plz? 
Cya! and thx
