title: Set a location to a Variable in PowerShell
body: <p>I'm very new to PowerShell, and I'm sure this is a simple question but I'm a little stumped.  I'm trying to open a Folder, sort by LastWriteTime, and open the Folder at the top of the list.  I want to store that in a variable so when I call the variable I can set my location to that variable.  The problem I'm having is that when I call my variable, nothing happens:</p>
  
  <blockquote>
    <p>$latest = Get-Childitem C:\Main | Sort LastWriteTime -Descending |
    Select -First 1 | Invoke-Item</p>
  </blockquote>
  
  <p>How come I get an error when I try to '<code>Set-Location $latest</code>'?</p>
