URGENT::TimeLineLite simple cross dissolve fade in and out

[eco_bach]

Hi

Not quite an expert yet with Timeline Lite but have a lite timeline (pun intended) for an as2 banner ad project.

In the following my clip fades in, but doesn't fade out....can anyone tell me why???

 

//CODE START

 

var timeline:TimelineLite = new TimelineLite();

timeline.addLabel("f1b", 3);

 

 

timeline.append( new TweenLite(F1a, 1, {_alpha:"100"}) );

timeline.insert(new TweenLite(F1a, 1, {_alpha:"0"}), "f1b");

 

//CODE END

It's because you have your alpha value in quotations, which means it's going to be relative to the current value.
