$objForm = New-Object System.Windows.Forms.OpenFileDialog
$objForm.InitialDirectory = $Directory
$objForm.Filter = $Filter
$objForm.Title = $Title
$Show = $objForm.ShowDialog()
If ($Show -eq "OK")

Return $objForm.FileName
}
Else

Hello, "I can't get it to work": what's happening?
Have you tried putting the first line at the end? -
Yes, the problem is probably the first line. If I don't include it, there are no errors, and if I move it to the end, it doesn't change anything.
Here are my errors when I execute the entire code:
