I wasn't being very clear.

My problem exactly is that, I want to run a function of my MovieClip from my MainClass.

myMovieClip.DoYourFunction(withMyClassVariable)

and in the MovieClip's class :

public function DoYourFunction(WhatVariable:String) {

}

Again sorry for not being clear.

How can I do this scenario?

It is put on stage on one frame.

It gives me :

Property Match_Easy not found on ControlUnit and there is no default value.

ControlUnit is my main Class.

Match Easy is the movieClip which is on frame 4 of my timeline and it has it's AS Linkage as Match_Easy.

If I put an instane name for it I get this error:

 

Type was not found or was not a compile-time constant: Match_Easy.

What can I do. I'm frustrated.

Alright ...everything seems fine to me.

Here's the code in my Main Class :

public function BonusClicked(e:MouseEvent) {

            trace(currentFrame);

            MovieClip(root).Match_Easy.Hint(myBonus);

        }

And the code in Match_Easy :

 

public function Hint(WhatKind:String) {

            if (WhatKind == 'Time') {//Bonus ne kohe ...Hiqen disa sekonda.

                gameTime +=  TimeBonus;

            } else if (WhatKind == 'Score') {//Bonus ne pike ...Shtohen disa pike.

                gameScore +=  pointsForMatch;

            } else {//Bonus qe shfaq te gjithe letrat dhe me pas i kthen sic ishin.

                HintTimer = new Timer(250,2);

                HintTimer.addEventListener(TimerEvent.TIMER_COMPLETE, hideCards);//Hiqe kete me nje lloj menyre !?

                for (var i:uint = 0; i < BunchOfCards.length; i++) {

                    BunchOfCards[i].startFlip(BunchOfCards[i].cardface + 2);

                }

                function hideCards(e:MouseEvent):void {

                    for (var i:uint = 0; i < BunchOfCards.length; i++) {

                        BunchOfCards[i].startFlip(1);

                    }

                }

                HintTimer.start();

            }

        }

Methods are public, frame is 4 so movieclip exists.

Sorry but it seems I did something foolish before.

I put the instance name same as the class name. :S

Sorry and thank you.
