Adding wait functionality

programming flash
1

I have an application in which there is a class that reads an XML file into an array. This array contains a number of strings that are sent when the user performs an action. Some of the strings, however, are also special instructions to the application to do something like displaying a popup. Now, I’m trying to add a wait functionality where I can place a “wait:#” step into the XML file and have the app wait # seconds. I have been trying to work with the class to add this in, but it doesn’t seem to be working.
Here’s what I have for the code:


class images.classes.StepListMgr {
 ...
 ...variables here
 ...
 function checkFp(fp:String) {
  if (fp==stepArray[0]) {
   removeArrElmt(steArray, 0);
   checkSpecSteps();
   checkWaitStep();
  }
 }
 function checkSpecSteps() {
  //Check special step strings
  if (waitInt) {
   clearInterval(waitInt);
   waitInt = null;
  }
  check4Popup();
  check4EsdStartEnd();
  checkDone();
 }
 private function checkDone() {
  if (stepArray.length == 0) {
   _global.modDone();
  }
 }
 private function check4Popup() {
  if (stepArray[0].length == 1) {
   var step = stepArray[0][0].val;
   if (step.substr(0, 6) == "popup:") {
    var msgBox = step.substr(6);
    var popUpParams = msgBox.split(":");
    removeArrElmt(stepArray, 0);
    _global.CallPopUp(popUpParams[0], popUpParams[1]);
   }
  }
 }
 private function check4EsdStartEnd() {
  if (stepArray[0].length == 1) {
   var step = stepArray[0][0].val;
   if (step.substr(0,3)=="esd") {
    if (step.substr(3)=="Start") {
     _global.esdNow = true;
    } else if (step.substr(3)=="End") {
     _global.esdNow = false;
    }
    removeArrElmt(stepArray, 0);
   }
  }
 }
 function checkWaitStep() {
  var step = stepArray[0][0].val;
  if (step.substr(0,5)=="wait:") {
   numSecs = Number(step.substr(5))*1000;
   waitInt = setInterval(checkSpecSteps,numSecs);
  }
 }
}

It seems like the interval waitInt is clearing before I want it to. Does anyone see what I’m doing wrong here?
