Assignment operator prevents concatenation - powershell

Question

I have AD groups named xxx16up, yyy16up, zzz16up. What I'm trying to do is if:
AD user is grade level 16 and up
AD user is not yet a member of said group
the script will add the AD user to the corresponding group based on company codes xxx, yyy, zzz.
$list = Import-CSV "C:\update12Apr2018.csv"
foreach ($company in $list) {
$myList = ( Get-ADGroup "$($company.comp)16up" ).DistinguishedName
if ( ([INT]$_.level -ge 16) -and (Get-ADUser -LDAPFilter "(!(memberof=$myList))" )) {
Add-ADGroupMember -Identity "$($company.comp)16up" -Members $company.samAccountName
}
}
The part highlighted does not work within the code. But if I take it out and run it by itself it has no problems. It produces the corresponding group of either xxx16up, yyy16up, or zzz16up.
Within the code, it gave below error:
Get-ADGroup : Cannot find an object with identity: '16up' under: 'DC=ACME,DC=com'. At line:1 char:33

I was able to narrow down the problem to when there is an assignment operation and that is when it acts as if the concatenation failed.

Answer 1

ForEach ($company in $list) {
$groupName = $company.comp + '16up'
$myList = ( Get-ADGroup $groupName ).DistinguishedName
see the sleight of hand? ;-)
