Another open door script in c#

Unity Engine
1

i copied this from a js script, it’s not working. Can anyone troubleshoot this? Thanks.

using UnityEngine;
using System.Collections; 

public class OpenDoor : MonoBehaviour 
{
	float smooth = 2.0f;
	float DoorOpenAngle = 90.0f;
	float DoorCloseAngle = 0.0f;
	bool open;
	bool enter;
	

	
 	void  OnTriggerEnter ( Collider other  )
	{ 
		if (other.gameObject.tag == "Player") 
		{
			enter = true;
			print("open");
		}
	}


    void  OnTriggerExit ( Collider other  )
	{ 
		if (other.gameObject.tag == "Player") 
		{
			enter = false;
			print("close");
		}
    }
	
	void update()
	{
		if(open == true)
		{
			print("if(open)");
 			var target = Quaternion.Euler (0, DoorOpenAngle, 0);
 			transform.localRotation = Quaternion.Slerp(transform.localRotation, target, Time.deltaTime * smooth);
		}
		
		if(open == false)
		{
			print("if(!open)");
 			var target1= Quaternion.Euler (0, DoorCloseAngle, 0);
 			transform.localRotation = Quaternion.Slerp(transform.localRotation, target1, Time.deltaTime * smooth);
 		}	
		
		if(enter == true)
		{
			print("if(enter)");
			if(Input.GetKeyDown("f"))
			{
				open = !open; 
			}
		}
	}
}

C# is case sensitive, so “update” should begin with a capital “U”. Just a fast reading though, there can be more issues.

Edit: Is the game starting? If yes, the solution above should work.
