Angle w/ trig

I have a game that I’m making, and regardless of other stuff, I need to make essentially a turret. I know how to code where it should move towards (that’s easy), and I know somewhat how to use math stuff on flash. But when I tried to implement it on this, it doesn’t work. See code:

angleA = Math.atan2(TARGET._y-HERO._y, TARGET._x-HERO._x);
var degrees = angleA/(Math.PI/360);
BULLET._rotation = degrees;

It is correctly placed, don’t worry about that.
