I am having a very hard time figuring out how to pass data between the multiple forms in a multiform project.

I find little to nothing in the way of help in your documentation. Is there anyone out there that has done this?

write-host statement after the If statement. I'm still not sure how you get the called form to return a value of "OK" . Need clarification on that.

FYI, you can always ignore the return value if you like. Use if only if you care if the user cancels an action or not. David

The return values are not the control, but the string. In this case you just use: Write-Host $Form1_TextBox1 David
