cannot fire second line renderer

Hello. I have two lineRenderers on two separate objects, but only one will fire, I have tried everything I could think of, and then everything the forums suggested. I don't think it is the input settings because other effects on the second object work fine. For reasons I cant comprehend when I fire the second one only the first one fires.

Here is the script for the line renderer;

using UnityEngine; using System.Collections;

public class laserleft : MonoBehaviour {

 public float laserStrength;



 //line
 private LineRenderer lineRenderer;


 // source
 private Transform shipzero;

 // hitpoint
 private RaycastHit hitpnt;

 // Use this for initialization
 void Start () {

     shipzero = gameObject.transform;

     lineRenderer = gameObject.GetComponent<LineRenderer> ();


     // The line is disabled
     lineRenderer.enabled = false;

     // world space i think is ok
     lineRenderer.useWorldSpace = true;

     // this will be over written by the options
     lineRenderer.SetColors( Color.cyan, Color.blue);
 }


 // Update is called once per frame
 void FixedUpdate () {



     // boolean says if it hits. it always will
     bool ifithits = Physics.Raycast (shipzero.position, Vector3.right, out hitpnt , 10000f);

     if (Input.GetButton ("Laser1")) {

         // turns on the line
         lineRenderer.enabled = true;


         lineRenderer.SetPosition (0, new Vector3( shipzero.position.x, shipzero.position.y, shipzero.position.z));
         lineRenderer.SetPosition (1, new Vector3(hitpnt.point.x, shipzero.position.y, shipzero.position.z));


     }
     else {
         lineRenderer.enabled = false;

     }




     // the physics

     if (hitpnt.collider.tag=="ball"){
         hitpnt.rigidbody.AddForceAtPosition(hitpnt.point, Vector3.right*laserStrength);
     }

     // the clause for the other ship
     if (hitpnt.collider.tag== "p1"){
         hitpnt.rigidbody.AddForceAtPosition( hitpnt.point, Vector3.right*laserStrength);
     }


 }

}

The script is pretty much the same for both objects, but facing the other way and calling different linerenderers.
