Hey, I can’t work out how to do this, but this is what I have so far…

onClipEvent (enterFrame) {  
radians = Math.atan2(\_root.\_ymouse-this.\_y, \_root.\_xmouse-this.\_x);  
degrees = (radians/Math.PI)\*180;  
\_rotation = degrees;  
}

How would I make it so that it can only point between 0 and 90 degrees? Thanks.
