Reveal and Un-reveal text upon clicking with animated transition

[Harionago]

I want to create a simple script in AS2 that can reveal and un-reveal some text upon clicking (and any additional graphic), preferably with a simple transition (likely a tween). How would I go about achieving this? As you can probably tell, I'm completely new to ActionScript, but have a rudimentary understanding of how to operate across Flash itself.

Any help would be appreciated.

try if this does what you are looking for (I'll try to make it as easy to understand as possible...):

- create a static text on your stage, anything you like.
- convert the created text-field into a MovieClip (Press F8) and name it mc_test
- select the MovieClip and in the properties window, give it the instance-name "test" (without quotes).

- draw a box anywhere on your stage (this will be our button)
select the whole box and press F8 to convert it to a movieclip.
- select the MovieClip of the box and in the properties-window, give it the instance-name "button" (again without qoutes).

- create a new leyer in your main-scene and name it actions.
- select the first frame on layer "actions" and press F9 to open the actions-panel
- try the next piece of ActionScrip 2.0 code:

_root.button.onRelease = function(){
    var steps:Number = 10;
    var stepsize:Number = 100 / steps;
    if(invisible == true){
        action = "showit";
        invisible = false;
    } else {
        action = "hideit";
        invisible = true;
    }
    onEnterFrame = function(){
        if(action == "hideit"){
            _root.test._alpha = 0 + (stepsize * steps);
        }else {
            _root.test._alpha = 100 - (stepsize * steps);
        }
        if(steps <= 0){
            delete(onEnterFrame);
        }
        steps--;
    }
}
