title: If false, do nothing?
body: <p>I'm attempting to make an excel formula do nothing if a cell is blank, is this possible? </p>
  
  <p>This is the formula as it stands, could I nest an if statement that checks if F4 &amp; G4 are blank and if they are it doesn't perform this formula? </p>
  
  <pre><code>=IF(F4 &lt; G4, G4 - F4, TODAY() - F4)
  </code></pre>
  
  <p>...</p>
  
  <p>Thanks!</p>
