title: How set a variable as a parameter value in JMeter
body: <p>I'm trying to set a variable as a parameter value in a Backend Listener. I tried to add the variable as</p>
  <blockquote>
  <p>${&quot;testname&quot;}</p>
  </blockquote>
  <p>and also as</p>
  <blockquote>
  <p>$[&quot;testname&quot;]</p>
  </blockquote>
  <p>but both options didn't work. JMeter consider them as a string and not as a variable. Any ideas how I can do that ?</p>
