title: if function used to update vaules broken
body: <p>I am trying to get the value <code>n</code> to update but it will not work for some reason. The code I have so far is:</p>
  
  <pre><code>if (coloum.Text == "1")
  {
      if (i &gt; s1)
      {
          MessageBox.Show("There are " + s1 + " stones left in this column.");
      }
      else
      {
          s1 = s1 - i;
          coloum.Text = "";
          stones.Text = "";
          n = n + 1;
          if  (n == 3)
          {
              n = 1;
              player.Text = "Player " + n;
          }
  </code></pre>
  
  <p>The <code>if (coloum.Text == "1")</code> is true so the statement runs and <code>if (i &gt; s1)</code> then the message box shows:</p>
  
  <pre><code>s1 = s1 - i;
  coloum.Text = "";
  stones.Text = "";
  </code></pre>
  
  <p>This part is also updated however my <code>n</code> value will not update at all.</p>
  
  <p>I have declared <code>private int n;</code> at the start</p>
