Problem with camera and gun in FPS game

Hi! I'm working on a FPS game and I'm having some problems with the guns and the camera in the multiplayer.

void Awake()

{

players = GameObject.FindGameObjectsWithTag("Player");

foreach(GameObject player in players) {

if (player.networkView.isMine)

if(transform.parent = player.transform)

playerHolding = player; }

if (networkView.isMine) {

countToThrow = -1;

playerTransform = playerHolding.transform;

playerMovementScript = playerHolding.GetComponent();

camerasCheck = GameObject.FindGameObjectsWithTag("MainCamera");

foreach (GameObject cameraCheck in camerasCheck){

if(cameraCheck.networkView.isMine)

cameraObject = cameraCheck; }

}

else

enabled = false;

}

void LateUpdate ()

{ transform.position = cameraObject.transform.position + (Quaternion.Euler(0,targetYRotation,0)*new Vector3(holdSide*ratioHipHold + currentGunBobX, holdHeight*ratioHipHold + currentGunBobY, 0) + Quaternion.Euler(targetXRotation, targetYRotation,0)*new Vector3(0,0, currentRecoilZPos));

targetXRotation = Mathf.SmoothDamp(targetXRotation, cameraObject.GetComponent().xRotation, ref targetXRotationV, rotationSpeed);

targetYRotation = Mathf.SmoothDamp(targetYRotation, cameraObject.GetComponent().yRotation, ref targetYRotationV, rotationSpeed);

transform.rotation = Quaternion.Euler(targetXRotation, targetYRotation, 0);

This is the script that im using for guns in the fps, but when I try to use it on multiplayer the guns start moving crazy and when I shoot when the player that started the scene after the 1st player it looks like if the 1st player is shooting.

I didn't put the whole script cause it's really long.

Thanks!
