title: Need to create custom validation in Qualtrics limited to format "xx.x%"
body: <p>I'm trying to create custom validation in Qualtrics using "matches regex" (though i'm open to any other alternatives which achieve the same result in Qualtrics).  The allowed format should be: x.x, xx.x, x.x% or xx.x%</p>
  
  <p>For example, 8.4 or 8.4% should be allowed.  I've tried the following:</p>
  
  <pre><code>^\d{1,2}(\.\d{1})?%?$
  
  ^[0-9]{1,2}([\.][0-9]{1})?[\%]?$
  </code></pre>
  
  <p>Both seem to work fine in an online regex tester (<a href="https://regex101.com/" rel="nofollow">https://regex101.com/</a>) but I can't get them working in Qualtrics which seems to treat anything submitted as invalid.  </p>
  
  <p>Any suggestions would be greatly appreciated.  </p>
