title: excel min of a subset of a range
body: <p>I have an excel sheet with two columns of interest Year and Donations. The year values are 2008,2009,2010 etc...</p>
  
  <p>I would like to get the minimum of all donations for 2009. I have tried</p>
  
  <p>MIN(IF(Year="2009",Donations,"")</p>
  
  <p>The problem with this is for years other than 2009 it falls to "" and hence the min is 0.</p>
  
  <p>Is there a different function I should be using.</p>
