Someone to the rescue please!

hi i was wondering if someone could help me with code?

i have buttons on the main stage which i want to control the loading of a movie clip in to a container movie clip on the stage. however, i want to fade in (alpha 0>100) each clip on press of one of the buttons, and fade out the current movie clip in the container (100>0).

b1.buttText.buttonText.text = "ABOUT US";
b1.onPress = function() {
function which loads clip "x" on fade + unloads current clip "y" with fade out
};

i have the buttons “nested” within a container movie clip on the stage as there are some transitions applied to the buttons, not sure how this would affect the potential code.

hope someone can help! :wt:
