Adobe Flash CS3 Join Games?

Hi all.
Currently at college we are doing games development unit. We have to make a game in flash to demonstrate we can do it.
Now i have created the first game with ease which is basically a game where you just click on box's and you either win or lose. but i am curious because the other game is a basic version of space invaders. this has a scoring system and it changes and displays your final score when you die, i am just wondering if there would be a way to put this score system into the first game. just wondering if anyone could point me in the right direction really. the codes are below :d

Treasure game - no scores



var intRandom:int = 0;
var bolNewGame:Boolean = false;
reSet();

function reSet():void
{
mcpwin1.visible = false;
mcpwin2.visible = false;
mcpwin3.visible = false;
//this hides the "win" symbols

mcplose1.visible = false;
mcplose2.visible = false;
mcplose3.visible = false;
//this hides the "lose" symbols

btnbutton1.visible = true;
btnbutton2.visible = true;
btnbutton3.visible = true;
//this shows the three buttons

bolNewGame = false;
}

function Random3(event:MouseEvent):void
{

intRandom = Math.floor(Math.random()*3);
reSet();
txtmessage.text = "This is a new game, Click a box and see if you can find the missing money";
}

// what happens if button1 is pressed
function button1(event:MouseEvent):void
{
if (bolNewGame == false)
{
if (intRandom == 0)
{
txtmessage.text = "WAAAAHAYYYY, You found it :D Click the button to have another go!";
btnbutton1.visible = false;
mcpwin1.visible = true;
}
else
{
txtmessage.text = ":( Damn where could it be, Click the button to have another go";
btnbutton1.visible = false;
mcplose1.visible = true;
}
}
bolNewGame=true;

}

// what happens if button2 is pressed
function button2(event:MouseEvent):void
{
if (bolNewGame == false)
{
if (intRandom == 0)
{
txtmessage.text = "WAAAAHAYYYY, You found it :D Click the button to have another go!";
btnbutton2.visible = false;
mcpwin2.visible = true;
}
else
{
txtmessage.text = ":( Damn where could it be, Click the button to have another go";
btnbutton2.visible = false;
mcplose2.visible = true;
}
}
bolNewGame=true;
}

// what happens if button3 is pressed
function button3(event:MouseEvent):void
{
if (bolNewGame == false)
{
if (intRandom == 0)
{
txtmessage.text = "WAAAAHAYYYY, You found it :D Click the button to have another go!";

{

}
}

}

btnreset.addEventListener(MouseEvent.CLICK, Random3);

btnbutton2.addEventListener(MouseEvent.CLICK, button2);
btnbutton3.addEventListener(MouseEvent.CLICK, button3);

any help will be greatly appreciated, i dont want to know how it should be i just really need a point in the right direction :)
p.s we are using Adobe Flash Pro CS3 - Actionscript 3 :d

The scoring variable of the space invaders is the var intScore:int = 0; on top of the code, where all variables are assigned. This variable gets increased in shotDown and shotDown2 functions where a collision between your shot and the alien has been detected.

Moving now to your treasure game, it's very easy to insert that variable increase below the lines you say "WAAAAHAYYYY, You found it".
Of course you must still define the variable on top of your program in a global position (I believe you know already about variable scope and when variables are visible only inside a function or not).

Happy coding!
