How can I give another script my transform.

I have two scripts, target and movement. I want to give movement the transform of the gameObject that target is attached to. I can’t do this through the inspector because there is multiple of both objects and so I don’t think that’s possible. What I’m doing currently is using getComponent to access movement and there changing the transform variable it has to the transform of the gameObject.

void Start ()
	{
		target.position = transform.position;		
		script = gameObject.GetComponent<movement> ();		
	}

This is from the target script and I’m getting the transform of the attached gameObject and then getting access to the movement script.

void OnMouseOver ()
	{
		if (Input.GetMouseButtonDown (0)) 
		{
			Vector3 spawnPosition = new Vector3 (0,0,0);
			Quaternion spawnRotation = Quaternion.identity;
			Instantiate (policeCar, spawnPosition, spawnRotation);
			script.destination = target;
		}
	}

The last line is where I access the variable target in the movement script and set it as target.

    public Transform destination;
	private NavMeshAgent navComp;
	
	void Start () 
	{
		navComp = GetComponent <NavMeshAgent>();
	}

	void Update () 
	{
		navComp.SetDestination(destination.position);
	}

Finally, here is the simple movement script. So far I haven’t been able to make this work, so I was wondering if there was a simpler way of giving another script the transform?

script = gameObject.GetComponent ();

the movement script and the target script are attached to the same object? if so why not just use the transform from movemnt to stat with and if not then gameObject should be a variable, not gameObject
