Referencing Scripts properly and still not working? Help!

Okay so I need to fix the scoring for my game. I want score = (Time x 10)+(count x 10) and I am referencing count from finishline script and Time from Player script. I dont understand why It not working? smh please help!

using UnityEngine;
using System.Collections;
using UnityEditor;

public class Score : MonoBehaviour 
{

	public GUIText TheScore;
	public float myScore;
	//Script Reference
//	public Clock myTimer;
//	public Finishline count;
	
	void Start()
	{
		GameObject Player = GameObject.Find ("Player");
		Clock2 Timer = Player.GetComponent<Clock2> ();

		GameObject finishline = GameObject.Find("finishline");
		Finishline count = finishline.GetComponent<Finishline>();
	}

	public int Timestop = Clock2.Timer.myTimer*10;

	public int Balls = Finishline.count*10;
	
	void Update()
	{
		if (Time >= 300) //why is myTimer isnt working?
		{
			myScore = Timestop + Balls;
		}
	
		if (count = 12) //why is count isnt working?
		{
			myScore = Timestop + Balls;
		} 
	}
}

Declare variables in Class then perform Find and GetComponent in Start().

If you declare a variable in Start() it only has scope within that function.

Is count a variable of Finishline script? Your GetComponent is stored in a variable count of Type Finishline, so if count is a variable of Finishline you would have

count.count*10.

This is bad naming. Try

private Finishline finishLineScript;
private GameObject finishline;

void Start()
{
    finishline = GameObject.Find("finishline");
    finishLineScript = finishline.GetComponent<Finishline>();
    //ETC
}

So,

Finishline.count*10;

becomes

finishLineScript.count*10
