Quiz using AS 2.0 - Frame not displayed

hi,

I am facing a unique problem with my file.

I am creating a simple quiz using AS 2.0, i am giving the facility of navigating back and forth between questions and the user can always change the options or answer as they wish.

I have completed this part and its working perfectly fine.

When i embed this script with my given UI interface, i am facing this problem, in the init part, i have given the script for navigating to the nextFrame().

[COLOR=Red]function init() {
arrUserAnswer = new Array();
for (var i = 0; i<arrCorrectAnswer.length; i++) {
arrUserAnswer* = null;
}
nextFrame();

}
init();[/COLOR]

i have kept total of 5 frames, frame 1 holds the script and navigation elements

from frame 2 to 5 i have placed 4 questions. and whenever i play the movie i should get the first question to be displayed automatically.

But i am getting just a blank screen instead of frame 2 in my case.

can anyone kindly suggest me whats my problem …

the same code is working perfectly fine without my UI interface with the same setup of 5 Frames.

cheers
