title: Count values in a column if the column header equals a specific value
body: <p>I'm trying to write a formula in Excel that will count items in an array that are greater than zero if the column header matches a specified value.  I'm using the COUNTIFS function, and I'm fine with the greater than zero criterion, but I'm struggling with the second criterion.  I've tried using the INDEX and MATCH functions, but I'm not having much success.  Is there a function or formula that will tell Excel to search a two-dimensional array and only count values in the column whose header matches a specific value?</p>
  
  <p>Thanks!</p>
