SetInterval or do I need a hit test?

Question

I've a flash piece that uses 6 "houses" (buttons) to display information about mortgage products.  The houses are displayed together in a movie clip that, when rolling over, the user gets a brief description of the product.  I've placed a setInterval to keep the text up for 3000 miliseconds after the cursor leaves a "house".  The problem is after they initially mouseover a house, the onRollover event seems to not hold the text visable.
Code:
on(rollOver){
    clearInterval(timer);
    clearInterval(timer2);
    _root.DisplayText("adjustable");
    _root.DisplayTextBg(1);
on(rollOut){
    clearInterval(timer);
    clearInterval(timer2);
    timer = setInterval(_root.DisplayText,3000);
    timer2 = setInterval(_root.DisplayTextBg,3000);
timer and timer2 are declared on the first frame, and this code is in each button.  The functions for displaying text and the background image are on the first frame:
function DisplayTextBg(fade){
    if (fade==1){
        for (i=0;i<100;i++){
            textBg1._alpha += 1;
    }else{
        textBg1._alpha = 0;
function DisplayText(product){
    //trace(product);
    switch(product){
        case "fixed":
            varLoader.load("fixed.txt");
            break;
        case "adjustable":
            varLoader.load("adjustable.txt");
            break;
        case "possible":
            varLoader.load("homepossible.txt");
            break;
        case "reverse":
            varLoader.load("reverse.txt");
            break;
        case "equity":
            varLoader.load("equity.txt");           
            break;
        case "heloc":
            varLoader.load("heloc.txt");
            break;
        default:
            prodIntro_text.htmlText = "";
            prodTitle_text.htmlText = "";
            //trace("default case");
What should I do to get the rollover to persist after the initial rollout?  Is there a requirement for hit test to make this work?  I clear the interval at all stages, so I'm not sure why this doesn't work.

I'll include the release code for each button as well:
//equity house button code
on(rollOver){
    _root.DisplayText("equity");
    _root.DisplayTextBg(1);
on(rollOut){
    _root.timer=setInterval(_root.DisplayText,3000);
    _root.timer2=setInterval(_root.DisplayTextBg,3000);
on(release){
    // determine location to add movieclip
    var middleX = this._x + 100;
    var middleY = this._y + 359; //existing mc Y
    // reposition the clip    
    _root.attachMovie("equityHouse_mc","equity1",second.getNextHighestDepth(),{_x:middleX,_y: middleY});
    _root.equity1._xscale = 1800;
    _root.equity1._yscale = _root.equity1._xscale;
    mx.transitions.TransitionManager.start(_root.equity1, {type:mx.transitions.Zoom, direction:mx.transitions.Transition.IN, duration:7, easing:mx.transitions.easing.Strong.easeOut});
    _root.houseNumber = 3;
    _root.mcName = "equity1";
    _root.linkageId = "fd6";
    _root.equity1.fadeOut(5);
    _root.gotoAndStop(2);
//heloc house button code
on(rollOver){
    _root.DisplayText("heloc");
    _root.DisplayTextBg(1);
on(rollOut){
    timer=setInterval(_root.DisplayText,3000);
    timer2=setInterval(_root.DisplayTextBg,3000);
on(release){
    // determine location to add movieclip
    var middleX = this._x-200;
    var middleY = 339; //existing mc Y
    // reposition the clip    
    _root.attachMovie("helocHouse_mc","heloc1",second.getNextHighestDepth(),{_x:middleX,_y:mi ddleY});
    _root.heloc1._xscale = 1800;
    _root.heloc1._yscale = _root.heloc1._xscale;
    mx.transitions.TransitionManager.start(_root.heloc1, {type:mx.transitions.Zoom, direction:mx.transitions.Transition.IN, duration:4, easing:mx.transitions.easing.Strong.easeOut});
    _root.houseNumber = 3;
    _root.mcName = "heloc1";
    _root.linkageId = "fd5";
    _root.heloc1.fadeOut(5);
    _root.gotoAndStop(2);
The other 4 buttons mirror this code with the variation being the attachmovie names changed to protect the innocent.
The second frame removes the movie clip with all houses and scales the attached movie clip with a fade at the end
The second frame code is:
function fadeFrame(mc:MovieClip) {
    mc._alpha -= 5;
    if (mc._alpha<=0) {
        mc.alpha = 0;
        gotoAndStop(3);
var faded = setInterval(this, "trans", 1500);
function trans() {
    clearInterval(faded);
    gotoAndStop(3);
Finally, after the movie clip had faded, the third frame is:
import flash.display.BitmapData;
var websort:Number;
var rateFile:String;
var dataLoader:LoadVars = new LoadVars();
removeMovieClip(mcName);
var pName:String = mcName.substr(0,mcName.length - 1);
trace(pName);
    switch(pName){
            case "fixed":
                websort = 1;
                break;
            case "adjustable":
                websort = 11;
                break;
            case "possible":
                websort = 2;
                break;
            case "reverse":
                websort = 3;
                break;
            case "equity":
                websort = 5;
                rateFile = "http://192.168.219.82/equity.asp";
                break;
            case "heloc":
                websort = 6;
                break;
dataLoader.ref = this;
dataLoader.load(rateFile);
var myBitmapData:BitmapData = BitmapData.loadBitmap(linkageId);
//trace(myBitmapData instanceof BitmapData); // true
var mc:MovieClip = this.createEmptyMovieClip("mc", this.getNextHighestDepth());
mc.attachBitmap(this.myBitmapData, mc.getNextHighestDepth());
dataLoader.onLoad = function(success){
    if (success){
        for(var i=0; i<websort; i++){
            //trace(this.ref["cntr"]);
                    this.ref["Terms"].text = this["Terms"+i]
                    this.ref["Points"].text = this["Points"+i]
                    this.ref["Rate"].text = (this["Rate"+i]);
                    this.ref["Apr"].text = (this["Apr"+i]);
                    this.ref["Conditions"].text = (this["Conditions"+i]);
    } else {
        trace("Error loading data");
Which removed the scaled/faded house clip and loads a static image and data related to the product from the database.
