Basic Enemy AI Script (Missing Field Exeptions)

Hey, I just made this java script for my enemy's AI:

Code (JavaScript):

1. var Distance;
2. var Target : Transform;
3. var lookAtDistance = 25.0;
4. var attackRange = 15.0;
5. var moveSpeed = 5.0;
6. var Damping = 6.0;
7.  
8. function Update ()
9. {
10.     Distance = Vector3.Distance(Target.position, transform.position.position);
11.    
12.     if (Distance < lookAtDistance)
13.     {
14.         looAt();
15.     }  
16.    
17.     if (Distance < attackRange)
18.     {
19.         attack ();
20.     }
21. }
22.  
23. function looAt ()
24. {
25.     var rotation = Quaternion.LookRotation(Target.position - transform.position);
26.     transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * Damping);
27. }      
28.  
29. function attack ()
30. {
31.     transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);
32. }

But Unity gives me this error displayed in the attached picture file
Any help greatly appreciated!

 

transform.position.position?

 

Yes that was the problem, really noob of me.
Though I have another problem, the model I have written this script for flies towards the player a little above the ground? What can I do to make him walk towards the player?

 

give it a rigidbody with gravity?
