ActionScript 2.0 :: [Flash 8] Getting Variables For Score Counting?

I am creating a simple game where you must remember the name of a number of people. On the stage is a table with faces. Text appears, asking who, for example, "Mike" is. You then have to click the correct face. The questions appear randomly.I have come this far, but what I want to do is the following:

1) Restrict the number of random questions, presumably by adding a variable, with the value incrementing by each question, and tells the movie clip to go to the "game results" frame when reaching a certain number.

2) Keep track of the number of questions answered correctly/incorrectly. I suppose this is also done easily by adding a value for number of incorrect answers, which is increased for each incorrect answer, with the amount of correct answers being calculated like (total number of questions)-(incorrect answers).

3) Display the number of correct and incorrect questions on the "game results" frame. For example "You answered X number of questions correctly, and Z number of questions incorrectly".

I know that the pieces of code below should be used, but I don`t know how to put it all together, or where to put it. I suppose the main code should be in the first frame, and some should be in the buttons.

Code:
var questionsAsked:Number;

Code:
myValue++;

Code:
if (questionsAsked == 20){
gotoAndStop("results");
}
