title: How to make a drop-down list for worksheets
body: <p>I have a total of five sheets in a workbook.  My task is to create a combo list button in the first sheet that will be able to point to the other four.  If a user chooses one of the sheet names then the button will automatically activate the chosen sheet.  It is unlikely that sheets will be deleted, though likely that sheets will be added.  </p>
  
  <p>I'm not even sure how to get the sheet names to show up on the combo list.</p>
