I’m not sure what you’re asking, since you’ve removed the If statement that was giving you problems. Are you just trying to detect whether the user has entered any text? If so, you have a couple of...

Good call! The if ($DName.TextLength -eq 0) { } worked perfectly. I was initially trying if ($DName.Text -eq $null) which wasn’t working.
