Thanks. That helped a lot. I just got a problem. Because, i don't know why but the for loop isn't working. So the counter isn't being incremented and when time is over it still continues displaying the questions. It doesn't even check whether the answers are correct or not. Do i have something wrong in the for loop? Thanks a lot for your help. :-)
