Trouble with switch in PowerShell

$searcher = New-Object System.DirectoryServices.DirectorySearcher($root)
$searcher.filter = "(&(objectClass=user)(sAMAccountName= $SAMName))"
$name = $searcher.findall()

Write-Output $ADUser.Name
Write-Output $ADUserDept
Write-Output $Deptcode

I am using the above code as a test script for a bigger project.  I thought all was working well until I enter a user name of someone in the Corporate Finance department.  

The correct name comes back.

The correct Department Name comes back

The code for Finance is returned.  

What am I missing here?
