title: Validation Rule in Property Sheet Not Doing Anything
body: <p>I am using MS Access 2016</p>
  
  <p>I have two dates, a start date and an end date. I want to make sure that the end date occurs after the start date so I wrote a validation rule in the Property Sheet. </p>
  
  <p>I wrote:</p>
  
  <pre><code>[End Date]&gt;=[Start Date]
  </code></pre>
  
  <p>However it does not work. If I put an end date that occurs before the <code>Start Date</code>, the entry is still valid.</p>
  
  <p>Any help will be appreciated.</p>

  <p>What I highlighted red is where I get the error:</p>
  
  <blockquote>
    <p>"Invalid SQL Syntax - cannot use multiple columns in a column-level
    CHECK constraint"</p>
