Any help with prevent camera from passing a specific coordinate?

Question

I try to prevent my camera from moving for ever, so I want to add somthing like "borders". I tried this, but it gives me errors. How should I fix it?

 if(Camera.main.transform.position >= Vector3(worldBorderX, transform.position.y, transform.position.z))
 {
     Camera.main.transform.position = Vector3(worldBorderX, transform.position.y, transform.position.z);
 }
 
 if(Camera.main.transform.position >= Vector3(transform.position.x, transform.position.y, worldBorderZ))
 {
     Camera.main.transform.position = Vector3(transform.position.x, transform.position.y, worldBorderZ);
 }
 
 if(Camera.main.transform.position <= Vector3(-worldBorderX, transform.position.y, transform.position.z))
 {
     Camera.main.transform.position = Vector3(-worldBorderX, transform.position.y, transform.position.z);
 }
 
 if(Camera.main.transform.position <= Vector3(transform.position.x, transform.position.y, -worldBorderZ))
 {
     Camera.main.transform.position = Vector3(transform.position.x, transform.position.y, -worldBorderZ);
 }

assuming you are using Javascript/UnityScript. You may also want to edit your original post and add the errors.

     if(Camera.main.transform.position.x >= worldBorderX)
     {
         Camera.main.transform.position.x = worldBorderX;
     }
      
     if(Camera.main.transform.position.z >= worldBorderZ)
     {
         Camera.main.transform.position.z = worldBorderZ;
     }
      
     if(Camera.main.transform.position.x <= -worldBorderX)
     {
         Camera.main.transform.position.x = -worldBorderX;
     }
      
     if(Camera.main.transform.position.z <=  -worldBorderZ)
     {
         Camera.main.transform.position.z = -worldBorderZ;
     }

or

 Mathf.Clamp( Camera.main.transform.position.x, -worldBorderX, worldBorderX );
 Mathf.Clamp( Camera.main.transform.position.z, -worldBorderZ, worldBorderZ );

http://docs.unity3d.com/Documentation/ScriptReference/Mathf.Clamp.html

The above is still a good answer, upvoted.
