Sorry for the late response, I had surgery.
We only have 1 screen and did not need additional screens. Just a pop up to show up on the same screen we have with 1 button to hide and allow them to continue editing, 1 button to close out of everything and not edit because they aren't supposed to yet.
In this case, for anyone interested, this is what the solution was.
Create a rectangle, label and 2 buttons. (group them) and on Visible named PopUp
On ScreenNew (our only screen) OnVisible - UpdateContext({PopUp:false})
No Button - OnSelect - UpdateContext({PopUp: false});RequestHide()
Yes Button - OnSelect - UpdateContext({PopUp: false})
For the actual dropdown choices onCHange, otherwise it would show up no matter what was chosen
If(ddFormType.Selected.Value="Booking", UpdateContext({PopUp: true}),
If(ddFormType.Selected.Value="Cancelled",UpdateContext({PopUp: true}),
If(ddFormType.Selected.Value="Proposal",UpdateContext({PopUp: false}))))
I also added a switch to the Label and yes/no buttons so that I could also use the same boxes for a different choice in the dropdown.
