will

This sounds easy but I think I'm just simply messing it up. I want to play from say label "01" to label "02" on a mouse over event then pause once it's at "02". Then on a mouse out event I want it to play "02" back to "01" then pause. I'm trying to use: timeline.tweenFromTo("00","01") but it continues to run. Please tell/show me the correct way to do this. I'm trying to make a navigation bar that fades in and out when moused over (And a lot more) Thanks!
