Action Script 3 - timeline skipping action

Hi.

I have a problem with my code. I want to make a home page and another 3 pages ( 1,2,3 ). When I click from home page to page 1, the prev-next arrows are working but if I want to jump from home page to page 2 or 3, the arrows stoped working ( it looks like the action from frame 2 is jumped and unreadable ). What can I do to make them work even if I want to jump from home page to page 2 or 3?

Here is the source scene:

and here is timeline screenshot:

Thanks.
