PowerShell Param ValidateSet Options with Spaces and Tabs

Question

First, I apologize for submitting another question regarding PowerShell and the completion of the tab. The StackOverflow system revealed some great questions with answers to this topic, but they all seemed too cumbersome to implement this simple New-ADComputerscript.

Parameters are collected in Splatorder to save the script for reading. The following correct code tab has been added to ISE, but it should be enclosed in double quotes.

Is there any native method in PowerShell to allow tabs to execute parameter sets that include spaces?

Param(
  [Parameter(Mandatory=$true)]
  [string]$Server,
  [Parameter(Mandatory=$true)]
  [ValidateSet('Env1','Env 2','Env 3')]
  [string]$Environment,
  [Parameter(Mandatory=$true)]
  [ValidateSet('Application','Database','File and Print','Web Server')]
  [string]$Type
)
$NewADitems = @{
  Name        = $server
  Path        = "OU=$Type,OU=$Environment,OU=Smaller DN string"
  Location    ='MySite'
  Description = "Test Description"
  ManagedBy   = "Huge Distingushed Name string"
  WhatIf      = $true
}
Write-Host @NewADitems

Used command and error received:
