title: Concatenate Returns in Sharepoint Wrokflow into single field update
body: <p>I have two lists in <em>sharepoint</em>: </p>
  
  <ul>
  <li>One is a list (#1) with two Columns: <em>Name</em> and <em>Birthday</em>.</li>
  <li>The other list (#2) has many columns, but organizes by birthday. <BR /><strong>For instance:</strong> <em>birthday</em>, <em>zodiac sign</em>, <em>names of people with that birthday</em>.</li>
  </ul>
  
  <p>I am trying to create a workflow such that whenever someone enters a new birthday into <strong>list #2</strong>, the names column is automatically populated with a concatenated string of names of people with that birthday from <strong>list #1</strong>.</p>
  
  <p><em>How can I achieve this?</em></p>
