Problem with passing variable to remote session

Hello I am using below scriptblock and have passed variable name “localfolderpath” where while testing path it is coming null . could you please suggest what I am missing here . Due to this we are unable to folder for users who do not have it on server.

$ScriptBlockDir = {
Param (
[string] $samAccountName )

            if( $Env:ComputerName -eq "fileserver101" ) {
                $LocalFolderPath = "H:\Users"
            else {
                $LocalFolderPath = "D:\Users"

            if( -not (test-path -Path "$LocalFolderPath\$samAccountName") ) {
                try {
					LogEntry "New Home Drive Folder"
                    $NewFolder = New-Item -Path $LocalFolderPath -Name $samAccountName -ItemType Directory
                    return 1
                catch {
					Write-Host "Failed with error"
                    return -1
			Write-Host "already exists"
			return 0

        $result = Invoke-Command -Session $PSSession -ScriptBlock $ScriptBlockDir -ArgumentList $samAccountName

As well as

Test by using a simple test 1st to get the hand of how remoting and variables works and go from there.

Test path using the local computer

PS C:\> Invoke-Command -ComputerName "localhost" -ScriptBlock {Test-Path C:\Windows}

Now add the path to a variable

PS C:\> $path = "C:\Windows"

Use the variable in your remoting session and it fails because the variable is local to your machine and not the remote machine.

PS C:\> Invoke-Command -ComputerName "localhost" -ScriptBlock {Test-Path $path}
Cannot bind argument to parameter 'Path' because it is null.
    + CategoryInfo          : InvalidData: (:) [Test-Path], ParameterBindingValidationException
    + FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.PowerShell.Commands.TestPathCommand
    + PSComputerName        : localhost

To get the local variable sent over to the remote machine you have to prefix it with “using”

PS C:\> Invoke-Command -ComputerName "localhost" -ScriptBlock {Test-Path $using:path}


just for your information
just removed logentry line from try block and it worked
logentry is a function we have to logs comments.

thanks for your reply
