ActionScript 3.0 :: Using Preloader To Load Up SWFs?

I have a preloader and I want it to load each section when called with this code:
Callback function:
caps_mc.btn_continue_mc.addEventListener(MouseEvent.CLICK, nextpls);
function nextpls(e:MouseEvent):void {
MovieClip(parent.parent).nextSWF("startPage", parent);}

The code above tells the preloader that it is finished with the startPage and in the preloader it should next load faq, but I get an error saying that nextSWF is not a function when it clearly is, Is it even possible to use a preloader to load up swfs in this way??

Preloader:
import flash.display.*;import flash.events.*;
import flash.net.URLRequest;
var loadedSWF:Loadervar progressPercent:Number;
function startLoad(SWFName:String):void { loadedSWF = new Loader(); loadedSWF.contentLoaderInfo.addEventListener(Event.COMPLETE, gameLoaded);
[Code] .....

Here is the error:
TypeError: Error #1006: nextSWF is not a function. at startPages_fla::MainTimeline/nextpls()[startPages_fla.MainTimeline::frame1:7]
