title: COUNTIFS with ISNUMBER and multiple criteria
body: <p>I'm trying to count if the following range is <code>"Y"</code> or <code>"S"</code> and contains numbers. I'm trying to exclude cells beginning with <code>"_PVxxxxx_"</code>.</p>
  
  <p>I cant use </p>
  
  <pre><code>COUNTIFS($A:$A,"&gt;0",$B:$B,"Y") + COUNTIFS($A:$A,"&gt;0",$B:$B,"S")
  </code></pre>
  
  <p>because the formula considers <code>"_PVxxxxx_"</code> to be more than <code>0</code> and includes them in the calculation. </p>
  
  <p>Can anybody help? Thanks alot!</p>
