Inside the ForEach loop, add a line to print the personalMessage variable using Write-Output.

PowerShell

$clients = @('Alice', 'Bob', 'Charlie')
$message = 'Thank you for attending the meeting!'

foreach ($client in $clients) {
    $personalMessage = "$client, $message"
    # Print the personalMessage
    # Your code here
