nEnterFrame = function () {
if (ansCounter eq 3) {
gotoAndPlay("prof", 1);
}

The above code will force open a new scene called "prof".
I've manage to do that, LOL.
Now, I've been trying since morning to make it open a popup window with a button called "Proceed". Once user press "Proceed", it will then move to the scene "Prof". Therefore, this time, I create a new layer called "PopUpWindows" and add a "Proceed" button on it. But it didn't work well.

How do I go about doing it? I've change the following line unsuccessfully.

gotoAndPlay("PopUpWindows", 1);
