Set Elevation Height utilising UI.MultipleInputForm ++ into Revit

Good Day, i had created a script which

first asked user whether each level elevation is the same height?
second using ‘ScopeIf’ to launch whether the output is yes or no?

Anyone is able to shed some light to launch the code and see whether it worked (my laptop cpu is incapable to launch it)? If doesn’t, please advise/provide healthy recommendations to my script.
