Any help is appreciated.

Below is the code for the test that I have on my powerpoint now. The scoring
is setup on the master so on each slide the person can see their scoring as
they proceed. When I try to put in the code to prompt for the username - the
code given in this post, the prompt works but then whenever the Begin button
on the first slide is clicked it will not advance and the values for the test
do not reset to zero.

The username should appear on the last slide to print as a certificate.
(This includes their scoring.)

Sub Begin()
SlideMaster.CorrectBox.Value = 0
SlideMaster.WrongBox.Value = 0
SlideMaster.ScoreBox.Value = 0
SlideMaster.AnswersBox.Value = 0
SlideShowWindows(1).View.GotoSlide 2
End Sub

Sub Rightanswer()
SlideMaster.CorrectBox.Value = SlideMaster.CorrectBox.Value + 1
SlideMaster.AnswersBox.Value = SlideMaster.AnswersBox.Value + 1
SlideMaster.ScoreBox.Value = Round(SlideMaster.CorrectBox.Value /
SlideMaster.AnswersBox.Value * 100, 2)
SlideShowWindows(1).View.Next
End Sub

Sub Wronganswer()
SlideMaster.WrongBox.Value = SlideMaster.WrongBox.Value + 1
SlideMaster.AnswersBox.Value = SlideMaster.AnswersBox.Value + 1
SlideMaster.ScoreBox.Value = Round(SlideMaster.CorrectBox.Value /
SlideMaster.AnswersBox.Value * 100, 2)
MsgBox "Incorrect.  Try again."
End Sub

Sub PrintResults()

ActivePresentation.PrintOptions.OutputType = ppPrintOutputSlides
ActivePresentation.PrintOut From:=3, To:=3
ActivePresentation.SlideShowWindow.View.Exit

End Sub
