title: Make countif ignore "- -" from continue
body: <p>I'm having trouble with a countif that I am using to count the number of entries in a range. The problem is that the range is populated with an array formula, and when the data changes the cells the array formula added a <code>=CONTINUE(...)</code> to now display <code>--</code> (minus minus) </p>
  
  <pre><code>=COUNTIF(C6:C, "&lt;&gt;")
  </code></pre>
  
  <p>Is there a way that the countif could be written to ignore cells with <code>--</code>?</p>
