Need someone to help resolve my array problem!

Hi, I am using the splice method to remove questions in an array as they are answered in the quiz. However, not sure if this is what is causing the problem but sometimes the array, although coded to show only the first dimension in the text field, will show all dimensions. THis happens randomly.

I would be so grateful if someone would look at my FLA. Its just a small quiz but something in my script is broken! Cant attach my FLA here cuz of the puny limit of 74kb, but will gladly send privately.
