title: Position Absolute's jQuery-Validation-Engine - Conditional Validation of form fields
body: <p>I am working with Position Absolute's Form validation engine.  </p>
  
  <p>I have a specific case for validation that I'm hoping this can solve for me.  I need to be able to make one field required based on the value of another field.</p>
  
  <p>For example:  </p>
  
  <pre><code>If country.dropdown = "USA", then state.dropdown is required.  
  </code></pre>
  
  <p>or</p>
  
  <pre><code>If country.dropdown &lt;&gt; 'USA" then state.dropdown is not required.
  </code></pre>
  
  <p>Do you think this is possible with JQuery Validation Engine?  If so, can you point me in the right direction?</p>
