title: Why isn't my IF Formula working when it comes to blank cells in Excel?
body: <p>I am using the following <code>IF</code> formula:</p>
  <pre><code>=IF(AH132&lt;&gt;&quot;&quot;,DAYS(TODAY(),AH132),&quot;&quot;)
  </code></pre>
  <p>But when it comes to a blank reference cell, the formula is still adding a value when it should not and I am wondering how to fix it or make it work.</p>
