Big "IF" statement problem!

programming flash
1

At least I thinks its the if statement. I have an FLV Playback Component and three buttons. The buttons change the source of the FLV Playback. It was working fine. When I added an ‘if’ statement to track what video was currently being played I now get an error that goes on and on forever. This is the code I had working before adding the ‘if’ statement.

my_FLVPlybk.source = "think_eng.flv";
my_FLVPlybk.addASCuePoint(3, "1st_switch");
my_FLVPlybk.width = 640;
my_FLVPlybk.height = 426;

my_FLVPlybk.addEventListener(VideoEvent.READY, ready_listener);
my_FLVPlybk.addEventListener(VideoEvent.BUFFERING_STATE_ENTERED, videoStart)
my_FLVPlybk.addEventListener(VideoEvent.COMPLETE, videoDone)
function videoStart(eventObject:VideoEvent) 
{
	my_FLVPlybk.visible = true;
	video1Main_mc.rectangle1_mc.x = -8.4;
	video1Main_mc.rectangle1_mc.alpha = 1;
	video1_btn.visible = false;
}
function videoDone(eventObject:VideoEvent)
{
	my_FLVPlybk.visible = false;
	video1Main_mc.rectangle1_mc.x = -161.4;
	video1Main_mc.rectangle1_mc.alpha = 0;
	video1_btn.visible = true;
}
function ready_listener(eventObject:VideoEvent)
{
	my_FLVPlybk.activeVideoPlayerIndex = 1;
    my_FLVPlybk.source = "tech_eng.flv";
    my_FLVPlybk.addASCuePoint(3, "2nd_switch");
    my_FLVPlybk.activeVideoPlayerIndex = 0;
	
	my_FLVPlybk.activeVideoPlayerIndex = 2;
    my_FLVPlybk.source = "people_eng.flv";
    my_FLVPlybk.addASCuePoint(3, "2nd_switch");
    my_FLVPlybk.activeVideoPlayerIndex = 0;
}

Then I added this after the ready_listener.

if (my_FLVPlybk.source == "think_eng.flv")
	{
		video1Main_mc.rectangle1_mc.x = -8.4;
		video1Main_mc.rectangle1_mc.alpha = 1;
		video1_btn.visible = false;
	}
	
	if (my_FLVPlybk.source == "tech_eng.flv")
	{
		video1Main_mc.rectangle1_mc.x = -161.4;
		video1Main_mc.rectangle1_mc.alpha = 0;
		video1_btn.visible = true;
	}
	
	if (my_FLVPlybk.source == "people_eng.flv")
	{
		video1Main_mc.rectangle1_mc.x = -161.4;
		video1Main_mc.rectangle1_mc.alpha = 0;
		video1_btn.visible = true;
	}

Now I get this Error. The never ending one, it just keeps repeating.

TypeError: Error #1010: A term is undefined and has no properties.

Any help is much appreciated. I’m still new to AS3 so I’m not sure if it’s something really simple that I am doing wrong or complicated.

Thanks!
