Foreach group in managed unit

Hi,

I am a newbie to powershell nd would like some help with the below if please.

We have active roles 6.7.

I have a managed unit called delegation unit,

only security group objects exist in it.

what I am trying to achieve is for each group in the managed unit, count members in it and the write this number on the description of the group.

the script work's from a quest powershell command window, however if I import the script into active roles as a scheduled task script and then schedule it it get's an error.

script is as below.

$testgroups = Get-QADGroup -proxy -SearchRoot "Configuration/Managed Units/DelegateMU/Test_GroupsCount"

Foreach ($Testgroup in $TestGroups)

{

$Counter = @(Get-qadgroupmember $VDETestgroup -enabled).count

        Set-qadgroup -proxy $Testgroup -description "$counter : Enabled users in group"

}

Thank you in advance

M.
