title: Returning multiple values using Vlookup in excel
body: <p>I have an excel sheet set up to automatically calculate meetings per day by day of the week.  I would like to write a formula to return all dates I have a meeting scheduled (comma separated preferably), but I am having some difficulty.  Using Vlookup, I can only get it to return the first date.</p>
  
  <p>For example, here is what my data looks like:</p>
  
  <pre><code>         A                                 B                            C
   Initial Meetings          Follow-up Meetings            Date
           1                                1                       7/29/2015
           0                                1                       7/30/2015
           1                                1                       7/31/2015
           0                                0                       8/1/2015
           0                                0                       8/2/2015
  </code></pre>
  
  <p>I would like to write a formula to return "7/29/2015, 7/31/2015" in one cell, and "7/29/2015, 7/30/2015, 7/31/2015" in another, but I seem to be stuck.</p>
