.... does not contain a definition for ...

Hi. I’m having a problem with a script in Unity 5. I use C# :
Assets/Scripts/Tetromino.cs(73,76): error CS1061: Type Tetromino' does not contain a definition for position’ and no extension method position' of type Tetromino’ could be found (are you missing a using directive or an assembly reference?)
WARNING: Too much unused lines.
These are my scripts:

using UnityEngine;
using System.Collections;

public class Game : MonoBehaviour {

public static int gridWidth = 10;
public static int gridHeight = 20;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

}

public bool CheckIsInsideGrid (Vector2 pos) {

	return ((int)pos.x >= 0 && (int)pos.x < gridWidth && (int)pos.y >= 0);
}

public Vector2 Round (Vector2 pos) {

	return new Vector2 (Mathf.Round(pos.x), Mathf.Round(pos.y));
}

}

using UnityEngine;
using System.Collections;

public class Tetromino : MonoBehaviour {

float fall = 0;
public float fallSpeed = 1;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {

	CheckUserInput ();
}

void CheckUserInput () {

	if (Input.GetKeyDown(KeyCode.RightArrow)) {
	
		transform.position += new Vector3(1, 0, 0);
		
		if (CheckIsValidPosition()) {
		
		} else {
			
			transform.position+= new Vector3(-1, 0, 0); 
		}
	
	} else if (Input.GetKeyDown(KeyCode.LeftArrow)) {
	
		transform.position += new Vector3(-1, 0, 0);
		
		if (CheckIsValidPosition()) {
		
		} else {
			
			transform.position+= new Vector3(1, 0, 0);
		}
	
	} else if (Input.GetKeyDown(KeyCode.UpArrow)) {
	
		transform.Rotate (0, 0, 90);
		if (CheckIsValidPosition()) {
		
		} else {
		
			transform.Rotate (0, 0, -90);
		}
	
	} else if (Input.GetKeyDown(KeyCode.DownArrow) || Time.time - fall >= fallSpeed) {
	
		transform.position += new Vector3(0, -1, 0);
		
		fall = Time.time; // Ca sa nu mai cada imediat
		
		if (CheckIsValidPosition()) {
		
		} else {
			
			transform.position += new Vector3(0, 1, 0);
		}
	}
}

bool CheckIsValidPosition () {

	foreach (Tetromino mino in transform) {
	
		Vector2 pos = FindObjectOfType<Game>().Round (mino.position); // HERE is the error
		
		if (FindObjectOfType<Game>().CheckIsInsideGrid (pos) == false) {
			return false;
		}
	}
	return true;
}

}

Thank you!

The problem is this statement

foreach (Tetromino mino in transform)

even though it should look more like this

foreach (Transform mino in transform)

it does not make much sense because you are using foreach with transform.
