title: Translating a nested if statement into a set analysis expression
body: <p>I'm trying to translate this nested if statement into set analysis expression.</p>
  
  <pre><code>=Sum(if(Project=96,WorkTime*39.273,if(Project=92 and WorkType&lt;&gt;65,WorkTime*32.426,WorkTime*42.251)))
  </code></pre>
  
  <p>This is what I've done</p>
  
  <pre><code>=Sum({$&lt;Project={96}&gt;}WorkTime*39.273) or Sum({$&lt;Project = {96}, WorkType -={65}&gt;} WorkTime*32.426) or Sum({$&lt;Project = {96}&gt;} WorkTime*42.251)
  </code></pre>
  
  <p>I get an error near <code>WorkType -= {65}</code>, the problem is the operator. I've tried it even with &lt;>, still an error.</p>
