Writing a Class for making the 'enemies' follow the 'player'...

Question

Greetings;
I'm an actionscript beginner and trying  to write a class to  make the 'enemies' follow the 'player' (shown below). I'm trying to write it such that it takes two MovieClips as arguments, and moves the first one toward the second one. When I import the Class try to use it in Main.as by typing  " var followPlayer:FollowPlayer = new FollowPlayer(fishMov0, player);", I get the following error:
"ArgumentError: Error #1063: Argument count mismatch on jab.enemy::FollowPlayer/followPlayer(). Expected 2, got 1."
Any ideas/suggestions would be appreciated.
Thanks,
Jeremy
package  jab.enemy
    import flash.display.MovieClip;
    import flash.events.Event;
    public class FollowPlayer
        private var _clip1:MovieClip
        private var _clip2:MovieClip
        private var speed:uint = 1.5;
        public function FollowPlayer(clip1:MovieClip, clip2:MovieClip): void
        // clip1 is the enemy, clip2 the player being followed.
            _clip1 = clip1;
            _clip2 = clip2;
            _clip1.stage.addEventListener(Event.ENTER_FRAME, followPlayer);
            _clip2.stage.addEventListener(Event.ENTER_FRAME, followPlayer);
        private function followPlayer(_clip1:MovieClip, _clip2:MovieClip)
                if (_clip1.y > _clip2.y)
                    _clip1.y -= speed;
                if (_clip1.y < _clip2.y)
                    _clip1.y += speed;
                if (_clip1.x > _clip2.x)
                    _clip1.x -= speed;
                if (_clip1.x > _clip2.x)
                    _clip1.x -= speed;

Thanks guys! My code was seriously flawed, but I ended up getting it to work. For anyone else that might be interested, see 'FollowPlayer' below, an extremely simple class which takes two MovieClips as arguments, and moves the first one slowly (at 24fps) toward the second one:
package  jab.enemy
    import flash.display.MovieClip;
    import flash.events.Event;
    public class FollowPlayer
        private var _clip1:MovieClip
        private var _clip2:MovieClip
        private var speed = 1 + Math.random();
        public function FollowPlayer(clip1:MovieClip, clip2:MovieClip): void
        // clip1 is the enemy, clip2 the player being followed.
            _clip1 = clip1;
            _clip2 = clip2;
            _clip1.stage.addEventListener(Event.ENTER_FRAME, onEnterFrame)
            function onEnterFrame(event:Event):void
                if (_clip1.y > _clip2.y)
                    _clip1.y -= speed;
                if (_clip1.y < _clip2.y)
                    _clip1.y += speed;
                if (_clip1.x > _clip2.x)
                    _clip1.x -= speed;
                if (_clip1.x < _clip2.x)
                    _clip1.x += speed;
