i tried can`t manage to, if possible please me. code wrote

dr_line.addeventlistener(mouseevent.click,drawln); var test:boolean;  function drawln(e:mouseevent):void{     test=true;     stage.addeventlistener(mouseevent.click,reportclick);    }  var sx,sy,fx,fy:int; var j:int; function reportclick(event:mouseevent):void  {     j=0;     j++;      if (test==true && j==1) {         sx=event.localx;         sy=event.localy;         }     j++;     test=true;     trace(j);     trace(test);     if (test==true && j==2) {         fx=event.localx;         fy=event.localy;         j=0;         test=false;         var  line:shape = new shape();         line.graphics.beginfill(0x00ff00);         line.graphics.moveto(sx,sy);         line.graphics.lineto(fx,fy);          this.addchild(line);         } } 

how should make work .. please me , !!!! ,and yes function reportclick should checked .... can`t going or when press dr_line button should active checked ....

you assigning j=0 in click handler... should in drawln instead. also, require 1 j++ in click handler.

but cleaner approach have 2 click listener point1clicklistener , point2clicklistener. should attach point1clicklistener in drawln. inside point1clicklistener remove listening clicks point1clicklistener , attach click listener point2clicklistener. again, when point2clicklistener gets called remove listening clicks point2clicklistner.
