title: Excel: Simplified SUMs with multiple sheets
body: <p>I am having troubel figuring this one out using <em>names</em>. To start, take this example</p>
  
  <pre><code>Sheet 1                       Sheet 2
                           |
      A           B        |    A           B
                           | 
      Labor       1000     |    Labor        200
      Material    1000     |    Material     200
                           |
      ...                  |    ...
                           |
      Labor        500     |    Labor        100
      Material     500     |    Material     100
  </code></pre>
  
  <p><strong>The Question</strong>: I'd like to be able to total the Labor and Material values up for <code>n</code> number of sheets. The default template starts with two (2) sheets but the user may add any number of sheets they would like.</p>
  
  <p><strong>The Problem</strong> (as I see it): The user can add as many <strong>"special"</strong> page specific item pricing lines to the top of the page. Below that, however, every section (the Labor/Material calculations) are uniformly offset.</p>
  
  <p>If anybody could help me out on this one I'd really appreciate it. Thanks in advance!</p>
