setInterval- Should be easy

[dtone314]

Hey all. So I'm making a website, all flash. I have a content window where my external .swf's are loaded into. I'm using kind of a verticle wiping look to transition between .swf's. I want my button to wipeout the current .swf (already set up) wait 2 seconds, then wipe in the .swf corresponding to the button I pressed. I'm a little confused on where to put the function, and exactly how to call it froma button.
I have this on the first frame of my movie:

code:

---

funtion newswait() {

	loadMovie("news.swf",this.contents.holder);

	trace("GOGOGOGO");

	clearInterval(myTimer);

}

myTimer=setInterval(newswait,1500);

---

...and I have this on the button that I want to call the function:

code:

---

on(press) {

//This wipes out the loaded .swf

	this.contents.holder.play();

//I want a 2 second wait here, then execute the function.

	newswait();



}

What am I doing wrong? Thanks in advance!
