I have an MC with the registration point set to the Top Right so it will scale down and left:

function dragMC(e:Event){  
my\_mc.width = Stage.width - mouseX;  
my\_mc.height = mouseY;  
}

The MC i want to drag and scale has the following coords:

my\_mc.x = 636.65;  
my\_mc.y = 44.5;  
my\_mc.width = 146.1;  
my\_mc.height = 108.6;

Im getting an error because of the settings for :

var grid:Rectangle = new Rectangle(10, 10, my\_mc.width,my\_mc.height);

Can anyone spot prob what im stupidly doing wrong! 🙂

Any help comments appricated!
