Cant Find The Variable In Another Script?

Hi :)

Rookie question, but I am trying to get the "speed" variable from a script called "CheckSpeed" in the "Player" game object. I have checked every spelling and it insists on saying: "'speed' is not a member of 'UnityEngine.Component'"

What am I doing wrong?

My Script So Far:

 var bullet : Rigidbody;
 var bulletSpeed = 100;
 var shipSpeed : float;
 
 function Update () {
     
     shipSpeed = transform.Find("Player").GetComponent("CheckSpeed").speed; // ???
     
     if (Input.GetMouseButtonDown(0))
     {
         FireGun();
     }
 
 }
 
 
 function FireGun()
 {
     var clone = Instantiate(bullet, transform.position, transform.rotation);
     
     audio.Play();
     
     clone.velocity = transform.TransformDirection(Vector3(0, 0, bulletSpeed + shipSpeed)); 
     
     Destroy (clone.gameObject, 3);
 
 }

This should be a very simple solution, but it has stumped me for a good hour. I have never got the hang of referencing variables from other scripts/gameobjects. I wish I could just say stuff like "script.parent.parent.Part" :P

Also I'd like to add, I know this question has been asked a lot and there is a good page by Unity explaining a solution. But despite reading and following them, it doesn't seem to help.

Thanks :)
