I'm trying to use find and if statements how do I do this?,Im trying to use if statements with find how do I properly do this?

I agree with the above comment, you do seem to be lacking some serious fundamental understandings about C# itself. Perhaps following some unity tutorials will help. I am, however, a firm believer in just trying things out, so here is the script I would use to rotate an object once the object tagged with "Move" is past a certain point, with plenty (maybe too many) comments to explain why I am doing what I am doing

 //General note on C# convention - classes and functions should be capitalized
 //Variables should not be capitalized
 //While it seems like it doesn't matter now its a really good habit to get into because it makes your code much easier to read
 
 public class Scale : MonoBehaviour {
     
     GameObject move;
     public float speed = 5f;
 
     // Start is called before the first frame update 
     void Start () {
         //Good job calling this in the start function, it is much more efficient than calling it every update frame
         //Make sure you are using the correct function name however - FindWithTag is not what you want
         move = GameObject.FindObjectWithTag ("Move");
     }
 
     // Update is called once per frame
     // Use update here. FixedUpdate is used for physics calculations, and while not technically incorrect will just make it more complicated for you
     void Update () {
         //I have an object called move and I want to read its position
         //In other words I want the transform that belongs to move
         //Then I want the position that belongs to the transform
         //Then I want the x component of that position
 
         //This will set xValue equal to the position along the x axis of the move object
         float xValue = move.transform.position.x;
         //Now we can check if that value is less than our threshold value
         if(xValue < -4){
 
             //localScale contains information about the SIZE of the object
             //if you want to rotate, use rotation
             //in our case, instead of accessing the rotation directly we can use Transform.Rotate
             //lets first figure out how much we want to rotate around each axis
             Vector3 rotationAroundEachAxis = new Vector3(speed*Time.deltaTime, 0, 0);
             //Multiplying speed by Time.deltaTime is good here because we will get a constant speed regardless of the frame rate we are getting
             //This rotation is just a rotation around the x axis. Notice how the y and z values are zero
 
             //Now we just need to feed these values into the function
             //Notice we are calling the Rotate method that belongs to the transform component attached to this game object
             transform.Rotate(rotationAroundEachAxis);
         }
     }
