setInterval, clearInterval problems

[Liquid Genius]

Hi folks,

I seem to be creating a loop with setInterval, even though I am using clearInterval. The deck MC and btnQuit MC appear repetitively. I see this same problem quite a few times in the forums but cannot find a solution. Here is the code:

function processInitial() {
	trace("Begin processInitial()");
	for (i=0; i<=87; i++) {
		_root.allCardIDs[i] = _root.initialVars["c_id"+(i+1)];
	}
	for (i=0; i<=87; i++) {
		_root.allCardNames[i] = _root.initialVars["c_name"+(i+1)];
	}
	_root.deckOrder = Math.round(Math.random()*88);
	// Tells the deck the first cardName to display
	trace("Random number is: "+_root.deckOrder);
	intervalID = setInterval(displayDeck, 3000);
	trace("Finish processInitial()");
}

function displayDeck() {
	trace("Begin displayDeck()");
	clearInterval(intervalID);
	_root.attachMovie("deck", "deck", 50);
	// 50 refers to the level 
	_root.deck._alpha = 0;
	_root.deck.cardName._alpha = 0;	
	_root.deck._x = 19;
	_root.deck._y = 174;
	_root.deck.customFade(100, 20);
	_root.deck.cardID = _root.allCardIDs[_root.deckOrder];
	_root.deck.cardName = _root.allCardNames[_root.deckOrder];
	intervalID = setInterval(displayQuitButton, 2000);	
	trace("End displayDeck()");
}

function displayQuitButton() {
	trace("Begin displayQuitButton()");
	clearInterval(intervalID);
	_root.attachMovie("default_button", "btnQuit", 51);
	// Create the QUIT button
	_root.btnQuit._alpha = 0;
	_root.btnQuit._x = 22;
	_root.btnQuit._y = 463;
	_root.btnQuit.customFade(100, 10);
	_root.btnQuit.buttonText = "QUIT";
	trace("End displayQuitButton()");
}

This version also creates an infinite loop, and clearInterval fails.

function timer(a, b) {
	var intervalID = setInterval(a,b);
}

function processInitial() {
	trace("Begin processInitial()");
	for (i=0; i<=87; i++) {
		_root.allCardIDs[i] = _root.initialVars["c_id"+(i+1)];
	}
	for (i=0; i<=87; i++) {
		_root.allCardNames[i] = _root.initialVars["c_name"+(i+1)];
	}
	_root.deckOrder = Math.round(Math.random()*88);
	// Tells the deck the first cardName to display
	trace("Random number is: "+_root.deckOrder);
	timer(displayDeck, 3000);
	trace("Finish processInitial()");
}

function displayDeck() {
	trace("Begin displayDeck()");
	_root.attachMovie("deck", "deck", 50);
	// 50 refers to the level 
	_root.deck._alpha = 0;
	_root.deck._x = 19;
	_root.deck._y = 174;
	_root.deck.customFade(100, 20);
	_root.deck.cardID = _root.allCardIDs[_root.deckOrder];
	_root.deck.cardName = _root.allCardNames[_root.deckOrder];
	clearInterval( intervalID );
	trace("End displayDeck()");
}

My output log reads as follows:

Begin initialize()
Sending and Loading
End initialize()
Initial variables loaded
Begin processInitial()
Random number is: 50
Begin timer()
End timer()
Finish processInitial()
Load status was: 1
Begin displayDeck()
clearInterval should have happened
End displayDeck()
Begin displayDeck()
clearInterval should have happened
End displayDeck()
Begin displayDeck()
clearInterval should have happened
End displayDeck()
Wash and repeat, etc, etc, etc, ad-nausium

I have also tried the original code using different variables for the intervalIDs. (ex: intervalID1, intervalID2) with the same results. Any help would be greatly appreciated!

Apparently, the scope of my clearInterval was incorrect I made sure that it was targeted to _root and everything works now! Answered my own question!

function processInitial() {
	trace("Begin processInitial()");
	for (i=0; i<=87; i++) {
		_root.allCardIDs[i] = _root.initialVars["c_id"+(i+1)];
	}
	for (i=0; i<=87; i++) {
		_root.allCardNames[i] = _root.initialVars["c_name"+(i+1)];
	}
	_root.deckOrder = Math.round(Math.random()*88);
	// Tells the deck the first cardName to display
	trace("Random number is: "+_root.deckOrder);
	_root.intervalID = setInterval(displayDeck, 3000);	
	trace("Finish processInitial()");
}

function displayDeck() {
	trace("Begin displayDeck()");
	_root.attachMovie("deck", "deck", 50);
	// 50 refers to the level 
	_root.deck._alpha = 0;
	_root.deck._x = 19;
	_root.deck._y = 174;
	_root.deck.customFade(100, 20);
	_root.deck.cardID = _root.allCardIDs[_root.deckOrder];
	_root.deck.cardName = _root.allCardNames[_root.deckOrder];
	clearInterval( _root.intervalID );
	_root.intervalID = setInterval(displayQuitButton, 2000);
	trace("End displayDeck()");
}

function displayQuitButton() {
	trace("Begin displayQuitButton()");
	_root.attachMovie("default_button", "btnQuit", 51);
	// Create the QUIT button
	_root.btnQuit._alpha = 0;
	_root.btnQuit._x = 22;
	_root.btnQuit._y = 463;
	_root.btnQuit.customFade(100, 10);
	_root.btnQuit.buttonText = "QUIT";
	clearInterval( _root.intervalID );
	_root.intervalID = setInterval(displayRefineButton, 2000);	
	trace("End displayQuitButton()");
}

function displayRefineButton() {
	trace("Begin displayRefineButton()");	
	_root.attachMovie("default_button", "btnRefine", 52);
	// Create the REFINE button	
	_root.btnRefine._alpha = 0;
	_root.btnRefine._x = 120;
	_root.btnRefine._y = 463;
	_root.btnRefine.customFade(25, 10);
	_root.btnRefine.buttonText = "REFINE";
	clearInterval( _root.intervalID );	
	trace("End displayRefineButton()");
}
