Solve Script class error

There is a problem that is new to me. I imported alot from Blender (models and animations) and everything was perfect. Now I imported my new enemy with 5 animations (I'm useing only 3 but its not the problem) and when i try to put the scrips on the enemy I get an error that say this:"Can't add script behaviour R.H.Control. The script file name does not match the name of the class defined in the script!" ("R.H.Control" is the name of the scrips I created for the enemy). Where/What is the problem??? What does it meen??

If the problem is in my script so please check it:

var distance; 
 var target : Transform;  
 var lookAtDistance = 160.0;
 var attackRange = 140.0;
 var deadRange = 100.0;
 var moveSpeed = 10.0;    
 var damping = 4.0;
 var shootTest = 0;
 //the var "shootTest" is for the effect of animation. after the enemy shoots, he put his gun away.
 //it to make shure that he will do it only after he shoot.
 static var ableFire = false;

 function Update ()   
 {  
     distance = Vector3.Distance(target.position, transform.position);
     if(distance < lookAtDistance)
     {    
         renderer.material.color = Color.yellow;
         animation.Play("GoingToShoot");
         lookAt ();   
     }   

     if(distance > lookAtDistance) 
     {   
         renderer.material.color = Color.green;
     }   

     if((distance < attackRange)&&(distance > deadRange)) 
     {   
         if (shootTest > 0)
         {
             animation.Play("StopShoot");
             shootTest = 0;
         }
         attack ();   
     }   

     if(distance < deadRange)
     {
         stop ();
         shootTest ++;
         ableFire = true;
     }
 }

 function lookAt ()
 {
     var rotation = Quaternion.LookRotation(target.position - transform.position);
     transform.rotation = Quaternion.Slerp(transform.rotation, rotation, Time.deltaTime * damping);
 }

 function attack ()
 {  
     ableFire = false;
     renderer.material.color = Color.red;   
     transform.Translate(Vector3.forward * moveSpeed *Time.deltaTime);
     animation.Play("R.H.Walk");
 }

 function stop ()
 {
     renderer.material.color = Color.black;
 }

Sorry for poor english...

Take away the dots, just put RHControl
