Hi Dianne1121 and welcome to the community.
Open Quizz / Quizz Preferances from the menu and check your
output options there, secondly, just check that your user
interactions (click boxes, text boxes etc.) have got points
assigned to them and that these points are to be added to the total
as a zero point assessment cannot return any results.
Hopefully the above will fix your problem.
Cheers
Andrew
