Rows & Columns of Sprites at runtime

I’m new to Unity. I’m trying to instantiate a 3x3 grid of cards with the following code. When I run this, I get cards all the way across and down the screen when I only expect a 3x3 grid. If I remove the loops and call Instantiate, I just get the single card like I expect. What am I doing wrong?

using UnityEngine;
public class BoardBuilder : MonoBehaviour
{
    public GameObject Card;
    public int width = 3;
    public int height = 3;

    void Start()
    {
        for (int y = 0; y < height; y++)
        {
            for (int x = 0; x < width; x++)
            {
                Instantiate(Card, new Vector3(x*25 - 100, y*-32 + 37, 0), Quaternion.identity);
            }
        }
    }
}

I figured this out. Moving the width and height inside the Start() method (and getting rid of the public scope) fixed it. I’m guessing that having the width and height as a public variables on the component, it’s pulling whatever the default width/height values are from the component and not the values I assigned to the variables.
