Whenever a movie clip envokes the following code it moves the whole stage, what gives?

function center (stageW, stageH) {  
this.centerStageX = Math.floor(stageW/2);  
this.centerStageY = Math.floor(stageH/2);  
this.speedX = (this.centerStageX-this.\_x)/4;  
this.speedY = (this.centerStageY-this.\_y)/4;  
this.\_x += this.speedX;  
this.\_y += this.speedY;  
}

I would appriciate it if whoever fixes this could also explain why this is happening so I know for the future, thank you all for you help.
