actionscript 3 - Error #1034, with a MouseEvent -

i making basic point n' click game , came upon error:
typeerror: error #1034: type coercion failed: cannot convert 3 cem.mouvement.

here's script:

package cem {     import flash.events.event;     import flash.display.movieclip;     import cem.microjeux.events.infojeuevent;     import cem.mouvement;     import flash.events.mouseevent;      public class monterjeu extends movieclip     {         private static var ptype:string = "type";         private static var pnom:string = "testnom";         private static var pcourriel:string = "test@hotmail.com";         private static var pdifficulte:int = 0;         private static var plangue:int = 0;         private static var ptitre:string = "veuillez sortir";         private static var pversion:string = "1.5";         private static var pcoordonnees:number;          private var environnementjeu:environnement = new environnement();         private var personnagejeu:personnage = new personnage();          public function monterjeu():void         {             jouer(pnom,pdifficulte,plangue);             dispatchevent(new infojeuevent(ptype,pnom,pcourriel,ptitre,pversion));             stage.addeventlistener(mouseevent.click, test);         }          public function jouer(pnom:string,pdifficulte:int,plangue:int):void         {             addchild(environnementjeu);             addchild(personnagejeu);         }         function test(e:mouseevent){             pcoordonnees = stage.mousex;             trace(pcoordonnees);             mouvement(3);         }     } } 

and on mouvement();

package cem {     public class mouvement {          public function mouvement(blabla) {             trace(blabla);         }     } } 

i searched everywhere could, , didn't find anything. have no instances on stage. imported on first frame. kind of beginner (let's i'm no @ programming), can notify @ same time if needs corrected. (btw, strange words in french ;d) thanks!

the error due trying cast 3 mouvement.

i think want like

function test(e:mouseevent){     pcoordonnees = stage.mousex;     trace(pcoordonnees);     var mouve:mouvement = new mouvement(3); } 

notice have have new in order create new instance of class.

on note, should capitilize classes stand out better. name class mouvement.
