Using Powershell to Update "manager" attribute in AD


I have a csv file that I use this to update all the AD attributes.

The CSV file looks like this:
11111,Engineer,22222,My Department,"111 main st., Suite 105",somecity,MD,22244

Below is the script I use to update the AD attributes:
Import-Module ActiveDirectory
Import-Csv update.csv | ForEach `
$mgr=Get-ADUser -LDAPFilter "(employeeID=$_.managerID)" | Select -ExpandProperty DistinguishedName
Get-ADUser -LDAPFilter "(employeeID=$_.employeeID)" -properties * |Set-ADUser -replace @{title=$title;manager=$mgr}

If I remove manager=$mgr the script works with no problems.

If I put it back it fails with error message:
Set-ADUser : Cannot bind parameter 'Replace' to the target. Exception setting "
Replace": "Object reference not set to an instance of an object."
At C:\temp\ad\userInfo.ps1:16 char:91
+     Get-ADUser -LDAPFilter "(employeeID=$_.employeeID)" -properties * |Set-AD
User -replace <<<<  @{title=$title;manager=$mgr}
    + CategoryInfo          : WriteError: (:) [Set-ADUser], ParameterBindingEx
    + FullyQualifiedErrorId : ParameterBindingFailed,Microsoft.ActiveDirectory

I tried putting quotes around $mgr but it still did not work.  
The weird part is if I type one by one on the powershell window it works fine.

Any ideas what the issue could be?

I don't know why it's different here, but the following works for me.  It seems that it is not detecting the variable as a string properly when trying to set the manager attribute.  I don't see the same issue when setting the title.
Get-ADUser -LDAPFilter "(employeeID=$_.employeeID)" -properties * |Set-ADUser -replace @{title=$title;manager="$mgr"}
# as does
Get-ADUser -LDAPFilter "(employeeID=$_.employeeID)" -properties * |Set-ADUser -replace @{title=$title;manager=[string]$mgr}

Open in new window

Also, you can just use the -manager parameter without issue.
Get-ADUser -LDAPFilter "(employeeID=$_.employeeID)" -properties * | Set-ADUser -manager $mgr

Open in new window
