powershell start-process

Good evening everyone,

I'm using a command line that passes arguments to as variables in the following scripts to be run in another ps1 that I'm calling from within this script. Whenever I try to pass the arguments from the command line I get the following error though

Start-Process : A positional parameter cannot be found that accepts argument

Would anyone be able to assist?
Thank you for your time and much appreciate any help. 

param
(
    [string]$targetserver = $args[0], #target server
    [string]$module = $args[1], #module name
)

function Get-Script-Directory
{    
  return Split-Path $script:MyInvocation.MyCommand.Path
}

Start-Process powershell.exe (Join-Path (Get-Script-Directory) "...\StopServices.ps1") -ArgumentList $targetserver $module

Try this for the last line 

$scriptPath = Join-Path (Get-Script-Directory) "...\StopServices.ps1"
Start-Process powershell.exe -ArgumentList "-file $scriptPath", $targetserver, $module
