title: SSRS Get a column value from a dataset
body: <p>I want to do something so simple that there is no reference to it on the internet!</p>
  
  <p>I have a dataset that returns a singe row:</p>
  
  <pre><code>Col1   Col2   Col3  Col3...
  abc    def    ghi   zzz...
  </code></pre>
  
  <p>I just want to display the value of Col2 (def) in a  textbox.
  I don't want to SUM() anything.
  I don't want to AVG() anything.</p>
  
  <p>How can I display the value of Col2 (def) in a  textbox.</p>
  
  <ul>
  <li>Fields!Col1.Value throws an error</li>
  <li>Lookup() throws an error.</li>
  </ul>
