title: What is the correct Syntax for "OR" condition inside "IF".?
body: <p>Have an if condition like below</p>
  
  <pre><code>if ((listbox != "lhs") || (listbox != "prevnext"))
  </code></pre>
  
  <p>This is failing even when listbox is "lhs" or "prevnext" string.</p>
  
  <p>Tried even below syntax but its failing</p>
  
  <pre><code>if ((listbox != "lhs" || listbox != "prevnext"))
  </code></pre>
  
  <p>Not sure of correct syntax for above condition.</p>
