I am trying to build a background alpha fade in and out.  
What i need is a file with 3 different buttons and 1 movieclip with 3 backgrounds.  
When i click on button 1 background 1 fade in from alpha 0 to 100 and when i click on button 2 background 1 fades out first to alpha 0 and then background 2 fades in from 0 to 100.  
Can somebody tell me how to build this ?  
Maybe a good tutorial tip
