In the code below there is a parameter named "$action" = {...}. Inside the brackets there are some variables ($path, $logPath, etc.) How can I access variables from this parameter outside of the braces "{}"? I need result of one of my functions("RunFunctions") for a while loop. Or if it's some stupid question please can you point me to the place where I can find some information about this {} notation? Thanks.

```
try {
    ### SET FOLDER TO WATCH + FILES TO WATCH + SUBFOLDERS YES/NO
    $watcher = New-Object System.IO.FileSystemWatcher
    $watcher.Path = "C:\Testers\ResetOptimisation\tracking"
    $watcher.Filter = "user_name*.*"
    $watcher.IncludeSubdirectories = $true
    $watcher.EnableRaisingEvents = $true

    ### DEFINE ACTIONS AFTER AN EVENT IS DETECTED
    $action = { $path = $Event.SourceEventArgs.FullPath
                $logPath = "C:\Testers\ResetOptimisation\output\log.txt"
                $changeType = $Event.SourceEventArgs.ChangeType
                $logline = "$(Get-Date), $changeType, $path"
                Add-content $logPath -value $logline
                $terminateFlag = RunFunctions $path $changeType $logPath
            }

    ### DECIDE WHICH EVENTS SHOULD BE WATCHED
    Register-ObjectEvent $watcher "Created" -Action $action
    Register-ObjectEvent $watcher "Changed" -Action $action
    Register-ObjectEvent $watcher "Deleted" -Action $action
    Register-ObjectEvent $watcher "Renamed" -Action $action
    while ($true) {
        Write-Host $teminateFlag
        if ($teminateFlag -eq 1) {
            Exit
        }
        Start-Sleep 3
    }
}
catch {
    Write-Host $_
}

```
