Need help!

Hey guys,
I’ve posted on here a few days ago about making an animation gradually animate over time. I’ve got 3 buttons. Each button when clicked reveals a series of images of varying sizes(collage) I’m using a tween class called mc_tween2 class found here and a for loop to gradually scale a mask revealing each image. I got all this working for the most part. Now my question is, when another button is clicked, i want the button to fade out, the collage to gradually scale back to its original position, then reveal the collage of the new button that was clicked. I guess i’m basically looking to do a smooth transition between button clicks. It has to be somewhat elegant and not too snappy. How can I get this to work? Setting an interval? A loop? I’m not even sure where to start…

I’m defintely an actionscript beginner and dont have the slighest idea on where to start projects like this. The code is definitely by far not the best coded, but i’ve learned a lot on this forum so far.

I’ve attached the file saved as Flash 8. Thanks for any help in advance!

Also one more thing. In the future, i might want to get the images loaded dynamically via XML but not exactly sure how i can get that to even work.
