title: if with -ne and -or operators not working in powershell
body: <p>The following if statements with -ne and -or operators is not working (Note I did not include the braces). $MyVariable is an integer coming in from a parameter in a function and having the if statement check the value. What I want is if <strong>$MyVariable</strong> is not equal to 16, 24 or 32 then return with error message otherwise continue. Calling the function as <strong>FunctionName 16;</strong> in the ps1 script.</p>
  
  <p>Function is defined as follows:</p>
  
  <pre><code>function FunctionName
  {
    param([Parameter(Mandatory = $false, Position = 0)]
              [AllowNull()]
              [int]   $MyVariable,
              [Parameter(Mandatory = $false, Position = 1)]
              [bool] $MyVariable2,
              [Parameter(Mandatory = $false, Position = 2)]
              [bool] $MyVariable3);
    if (...
  }
  </code></pre>
  
  <p>What am I doing wrong in the following if statements?</p>
  
  <pre><code>if ($MyVariable -ne 16 -or $MyVariable -ne 24 -or $MyVariable -ne 32)...
  if (16 -ne $MyVariable -or 24 -ne $MyVariable -or 32 -ne $MyVariable)...
  if (($MyVariable -ne 16) -or ($MyVariable -ne 24) -or ($MyVariable -ne 32))...
  </code></pre>
