Button inside of the scrollbox

Hello everyone. I feel so stupid and helpless, I cant even fall asleep. I am stuck
please help me.

Here is the problem i have a scroll box with thumbs inside it works great
those thumbs are buttons when a user clicks on them he should see a bigger image and then he can click on the next thumb and so on. The images are loading from the server.
The problem is nometer what i do the function which makes the click does not work
My fla is too big to post unfortunatly but here is how the relation works

and on that same level i am calling this[animalsMC.onPress = function(){
animalsMC.play();
]movie wich holds( big images+(-movie(which stores scrollbox (conteiner))-scrollbox(conteiner)-thumbs(buttons))
I will be so so so so glad if anyone would help me.

Thanks in advance
