title: Check to see if a variable is empty (multiple checks!)
body: <p>I am trying to run something if A is the same as B and B is not empty. I can do this check manually before I do thi -NE, but I rather do this in the same check.</p>
  
  <pre><code>if($($ADEmployee.mobile) -ne $($ListEmployee.mobile) -and (!$($ListEmployee.mobile)))
  {
    do someething
  }
  </code></pre>
  
  <p>can this be done?</p>
