Timing in OOP programming

Hi,

I need to get the order in which stuff happens in my first game right. Here is what I want to do.

1. Player clicks play button, button goes away and timer starts. //This is all working fine
2. Next I want a text box to animate for 60frames. //This works fine
3. ONLY then I want my next movie clips to start playing

How do I make step 3 wait for that 60 frames? I have no idea of how to code this.

Please help
