Pass script argument in Azure DevOps Pipeline which run a Powershell Script

Hi I have a simple Azure DevOps Pipeline

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:

- task: AzurePowerShell@5
  inputs:
    azureSubscription: 'Azure-DevOps'
    ScriptType: 'FilePath'
    ScriptPath: 'az-ps-scripts/session-07/vnet/vnet.ps1'
    ScriptArguments: '-RGNAME RunFmPp'
    azurePowerShellVersion: 'LatestVersion'
    workingDirectory: 'az-ps-scripts/session-07/vnet/'

As you can see it has a ScriptArguments: '-RGNAME RunFmPp' and it runs vnet.ps1 script.
But in fact, I do not know how can my vnet.ps1 script acces this argument from Azure DevOps.
This script create a Resource Group for Azure, I would like tho use -RGNAME here:

$rg = @{
    Name = $RGNAME
    Location = $vnetConf.Location
}
New-AzResourceGroup @rg -Force

But with $RGNAME it does not work, so does anyone know how can this script acces this argument from azure devops pipeline?

>Solution :

Declare your parameter(s) in a param() block at the top of your script:

param(
  [string]$RGNAME
)

$rg = @{
    Name = $RGNAME
    Location = $vnetConf.Location
}
New-AzResourceGroup @rg -Force
