This select case goes into a hotspot...
Thats up to u..what u want the user to do after they get their question..
The questions go into the select case...which is then put in a hotspot that the user clicks..however many times u want them too...
When the user clicks the hotspot..it says a question...then does whatever u want it too..
I"m not sure why u are asking about frames..and random frames...I thought u wanted random questions...
This select case gives u that..

and if you want the user to go to a frame per question..then u would add it to the select case..

Each time the user

He has added a random function to it..so they get the questions randomly...
