Resizing Movieclip in a restricted area.

Question

Dear friends,
I have 2 moveclip called view_mc and restricted    and button called btn_scale.
When the user click and drag btn_scale, it resizes the view_mc where the width and height of view_mc dosen't exceed the width and height/2 of restricted area.
I made that.  But when view_mc reaches the width and height/2 of restricted area, I can't resize view_mc to be samller.
(The btn_scale looks like it's disables and can't use it)
I think some logic is missing. I highlighted the code that is missing some logic.
var clickedX:Number;
var clickedY:Number;
var newScale:Number;
stage.addEventListener(MouseEvent.MOUSE_DOWN, on_stage_down);
stage.addEventListener(MouseEvent.MOUSE_UP, on_stage_up);
function on_stage_down(e:MouseEvent):void
if(btn_scale.hitTestPoint(stage.mouseX, stage.mouseY))
  clickedX = stage.mouseX - view_mc.x;
  clickedY = stage.mouseY - view_mc.y;
  newScale = view_mc.x;
  view_mc.addEventListener(Event.ENTER_FRAME, on_enter_scale);
function on_enter_scale(e:Event):void
stage.addEventListener(MouseEvent.MOUSE_MOVE, on_move_scale);
//////// Some Logic is missing here ////////
function on_move_scale(e:MouseEvent):void
if(view_mc.width < restricted.width && view_mc.height < restricted.height/2)
  view_mc.width = view_mc.height =  newScale * (stage.mouseY / clickedY);
function on_stage_up(e:MouseEvent):void
view_mc.removeEventListener(Event.ENTER_FRAME, on_enter_scale);
stage.removeEventListener(MouseEvent.MOUSE_MOVE, on_move_scale);
please help me solve this problem.
Thanks alot in advance.

Update the following code in your application...
function on_move_scale(e:MouseEvent):void
if(view_mc.width <= restricted.width && view_mc.height <= restricted.height/2)
  //Find new scale
  var temp = newScale * (stage.mouseY / clickedY);
  //Check if the new scale is within the limit or not?
  if(temp > restricted.height/2 || temp > restricted.width)
   //If its out of the limit update the scale to max value for scale.
   temp = (restricted.width)<=(restricted.height/2)?(restricted.width):(restricted.height/2);
  //Apply scale to MC.
  view_mc.width = view_mc.height =  temp;
//You should have a simillar check for the lower bound also ideally it will take only 0 as minimum scale value
