I am trying to make a quick script to add a AD group to a newly created Local server :

$ServerName = Read-Host 'New Server name?'
$ServerName|Foreach{
$GroupName = -join(“$_”,”-Admins”)
Write-Host $GroupName
Invoke-Command -computername $ServerName -scriptblock {Add-LocalGroupMember -Group 'Administrators' - 
Member $GroupName }
}

But I get the Cannot validate argument on parameter 'Member'. The argument is null or empty. Any suggestions? I have tried it several different ways and no joy.

you MUST pass the variables into a scriptblock when it is invoked that way. [*grin*] look at the `$Using:` scope modifier OR at adding parameters to the scriptblock. – Lee_Dailey Jul 27 '20 at 17:55
