Javascript controlling Mecanim?

Hi everyone,

My other problem was solved, but for some reason, one of my models is going into the ground when following my Player character. He has a collider, properly adjusted and all. I can't figure out the problem.

Here's my script:

 var Victim: Transform;         //target of robot
 var damp=1.0;                 //the speed at which robot turns
 var FireballPrefab:Transform;//the prefab for the projectile
 var savedTime=0;             //time since shooting
 var Tdist:float;              // distance between robot and Victim
 var moveSpeed=15;             //moving speed
 
 
 function Update()
 {
     //Initializing the animator component
     var Mek: Animator = GetComponent(Animator);
     
     //Variables for Shooting
     var seconds: int=Time.time;
     var oddeven=(seconds%2);            //seconds will make the oddeven  true or false
     
     //I have 2 parameters right now: Speed and Shooting
     if (Mek.GetBool("Shooting"))
     {
         Mek.SetFloat("Speed",0);
     }
  
     //finding dist
     if (Victim)
     {
         var Tdist = Vector3.Distance(Victim.position, transform.position);
         Mek.SetFloat("Tdist",Tdist);
     }
     
 
     //In range of Victim
     if(Tdist<100)
     {
         //looking at Victim
         var rotate = Quaternion.LookRotation(Victim.position-transform.position);
         transform.rotation=Quaternion.Slerp(transform.rotation,rotate,Time.deltaTime*damp);
     }
     //moving towards Victim
     if (Tdist>20 && Tdist<=50)
     {
         transform.Translate(Vector3.forward *moveSpeed* Time.deltaTime); //move forward
         Mek.SetFloat("Speed",moveSpeed); //setting Speed parameter
         Mek.SetBool("Shooting",false);     //shoot animation off
     }
     
     if (Tdist<=20)
     {
         Mek.SetFloat("Speed",0);        //Stop movement animation
         Mek.SetBool("Shooting",true);   //Start shooting animation
     }
     
     if (oddeven && Mek.GetBool("Shooting"))
     {    
         Mek.SetFloat("Speed",0);
         Shoot(seconds);                    //if oddeven is true and distance is <= than 20, call shoot function
     }
 }
     
 //Shooting Victim
 function Shoot(seconds)
 {
     
     if (seconds != savedTime)
     {
         var Fireball= Instantiate(FireballPrefab,transform.Find("TurretPoint").transform.position,Quaternion.identity);
     
         Fireball.rigidbody.AddForce(transform.forward*5000);
     
         savedTime=seconds;
     }
 
     
 }//End of Shooting function
