Thanks so much Lionz.
I've copied a link below to give you the layout and event sheet:
dropbox.com/s/h35fqced1akf9el/Quiz%20Game.c3p
Let me know if you have any issues accessing it.
I think I'm going wrong somewhere in my 'SetQuestions' function but I'm not 100% sure. It's finding the loopindex as I said earlier but you rightly guessed, it's only retrieving the end of the loop so the question won't change. I need the question to change when after an answer has been selected or if the countdown = 0. Hope this makes sense to you.
Sounds very simple to do but for some reason I just can't seem to get my head around it.
Thanks again for your help.
