title: Reference a variable within a variable in JMeter
body: <p>I'm working with JMeter. I'd like to specify the test host using user defined variables, like this:</p>
  
  <pre><code>variable name       value  
  localhost           localhost  
  test                192.168.0.1
  hostname            ${localhost}  
  </code></pre>
  
  <p>Executing the test, I see that the hostname value is not substituted, and obviously the test fails. I know I can use properties and pass the hostname from the command line, or simply change the hostname value. Is it possible to it like I've explained?<br>
  Thanks.</p>
