URGENT - Flash Timer Problem

Hey there, I;m having trouble to place a timer in my flash. I’m attaching the source file.

The issue is such that I’m having 3 buttons, when triggered (RollOver) reveals an image or swf and when I rollout, it display a default random image, from an image directory. What I want is to delay the action trigger over the 3 buttons such that it fades out again in let’s say 10seconds. Also, when the timer starts on any of the buttons I can rollover on any of the buttons and it overwrites the action from any previously rolled over buttons.

Does that make sense and anyone can help me please. This is urgent as I’m trying to solve this problem and deadline is end of this week.
