Roaming game ending scene help

[Lars!]

Hi first of all i hope you can help me, no one else could :(
I made an adventure game, where you colloct letters, you can move freely through all the scenes, and look for letters. Each letter is a Movie Clip, which contains the following code:

keyListener = new Object();

keyListener.onKeyDown = function() {
var keyCode = Key.getCode();

if (keyCode == 71) {
i = i + 1;
testi();
gotoAndStop(2);

}
};
Key.addListener(keyListener);

I want to load a scene when all the letters are collected (ending scene)
so i made a variable which is what the line: "testi();" refers to.
In my timeline i have tried to create a global variable with a function:

var (i = 0);

function (testi) {
if (i > 6)
gotoAndPlay(256)
}

There are 7 letters so far, which i why i want the "gotoAndPlay(256)" to load if i>6
But it doesent seem to work, is this a way to do it?
If this is not enough info, please tell me and i'll try to explain...

Thank you very much

You function is (or should be) in the top timeline. And form the movie clip you should call _root.testi().
Same thing for i. If you put code in the main timeline, you have to do _root.

If you're still lost, search google for actionscript+scope, and you should find a decent tutorial on scope.
