  #+TBLFM: $4=@0$-1/60::@6$3=vsum(@I..@II)
  </code></pre>
  
  <p>The main problem is the expression above that sums up total hours:</p>
  
  <pre><code>@6$3=vsum(@I..@II)
  </code></pre>
  
  <p>Should be something like:</p>
  
  <pre><code>@||+1$3=vsum(@I..@II)
  </code></pre>
  
  <p>So that as the spread sheet grows the last item in the second to last column will always sum the total. It doesn't work when I set it this way (and <code>+II</code>, and other ways) however.</p>
  
  <p>Any ideas?</p>
  
  <p>Thanks!</p>
