my code:

distancing\_mc.onEnterFrame = function() {

xdist = Math.round(\_root.\_xmouse - \_x);  
ydist = Math.round(\_root.\_ymouse - \_y);  
distancefromthis = Math.round(Math.sqrt((xdist_xdist) + (ydist_ydist)));  
circle\_mc.\_width = (100-distancefromthis)+20;  
circle\_mc.\_height = (100-distancefromthis)+20;  
}

I have a circle that gets larger/smaller depending upon where the mouse is in comparison to the circle. How would I set parameters so that the circle would shrink only to a certain size and also grow only to a certain size?
