title: Google Apps spreadsheet indirect sheet name?
body: <p>I have a Google Apps spreadsheet with three sheets, Y2013, Y2014, and table. </p>
  
  <p>On the table sheet I want to place the contents of cell B2 from either Y2013 or Y2014 depending upon which is in the contents of cell A1 on table i.e., A1 is either Y2013 or Y2014.  </p>
  
  <p>I have tried:

  ='&amp;A1&amp;'!B2.  </p>
  
  <p>What else might I try?</p>
