Having problems with a Switch!

Hey Guys, im trying myself on a first unity projekt: a 2D sidescroller game. However, i have some issues using a switch. I made a texture, added a box collider and a script that activates gameobject that were deactivated before OnTriggerEnter. Heres my code:

public GameObject target,target2,target3,target4;
public string tag = “Player”;

void OnTriggerEnter(Collider other)
{
	if (tag == "" || other.gameObject.CompareTag(tag))
{
	
}
}

void SchalterAwake()
{
			target.SetActive (true);
			target2.SetActive (true);
			target3.SetActive (true);
			target4.SetActive (true);
	}

The Problem is that my player doesnt activate OnTriggerEnter when he steps into the box collider, just nothing happens : / and thats really frustrating as i need this feature!

I hope you guys can help me : )

void OnTriggerEnter(Collider other)
{
if (tag == “” || other.gameObject.CompareTag(tag))
{

}
}

there is nothing inside the above. you have conditions, but nothing to perform. can you be trying this;

void OnTriggerEnter(Collider other)
{
    if (tag == "" || other.gameObject.CompareTag(tag))
{
        SchalterAwake();
}
}

Aw men im such a idiot, no wonder it wont work!!

Thanks a billion times : )!
