title: Counting items in a multi-dimensional array
body: <p>If I have the following array:</p>
  
  <pre><code>    Dim Array(4, 10) As String
      Array(0, 0) = "100"
      Array(0, 1) = "200"
      Array(1, 0) = "300"
      Array(1, 1) = "400"
      Array(1, 2) = "500"
      Array(1, 3) = "600"
  </code></pre>
  
  <p>How do I get the following count:</p>
  
  <pre><code>0 = 2
  1 = 4
  </code></pre>
