How to use a BrowseForFolder box in my powershell script?

Question

Hello,
I have the following script where I want to ask the user to select the folder they want the script to process the instructions from.  I've added a function for Select-Folder as follows:
function Select-Folder($message='Select a folder', $path = 0) {
$object = New-Object -comObject Shell.Application
$folder = $object.BrowseForFolder(0, $message, 0, $path)
if ($folder -ne $null) {
$folder.self.Path
Select-Folder 'Select the folder where the move scripts reside'
$files=Get-ChildItem $folder -Filter "*.txt"
foreach ($file in $files){
$outFileName=[IO.Path]::GetFileNameWithoutExtension($file.Name) + "_StartVMs.txt"
Get-Content $file.FullName | foreach{
Add-Content $folder\$outFileName "Start-ClusterResource ""$($_.Split('"')[1])"""
Issue #1:
The .txt files I am creating live in the same location as where this script lives. What I've found is the path I choose in the browseforfolder box that pops up is ignored and the files are converted in the location where the script lives.
Issue #2:
How do I get the Cancel button to work so the script will exit if the user selects Cancel?
Any help you can provide would be greatly appreciated.
Thank you.

Hi,
You're not setting a variable with the output of your function, so you don't have anything to test on. Give this slight modification a try (you'll need to work this back into your script, this is demo stuff only):
function Select-Folder($message='Select a folder', $path = 0) {
$object = New-Object -comObject Shell.Application
$folder = $object.BrowseForFolder(0, $message, 0, $path)
if ($folder -ne $null) {
$folder.self.Path
$folderPath = Select-Folder 'Select the folder where the move scripts reside'
Write-host "The selected folder path is $folderPath"
If ($folderPath) { Write-Host 'I have a folder, so keep processing in here' }
Else { Write-Host 'I do not have a folder path' }
