title: Excel input pop up box if cell is false
body: <p>I would like to make an excel worksheet to suit my needs of making word documents (mail merge).</p>
  
  <p>Can I use <code>IF</code> function like this:</p>
  
  <pre><code>IF(A1=Specific text;Write this text;RUN MACRO with popup box to input other text)
  </code></pre>
  
  <p>Basically, if value is true - write pre defined text and if it is false - give me pop up box to input new text?</p>
