Flash keeps throwing this error message at me:

Code:
TypeError: Error #2007: Parameter text must be non-null.
	at flash.text::TextField/set text()
	at rb_player_mini/video_status()
	at Function/http://adobe.com/AS3/2006/builtin::apply()
	at SetIntervalTimer/onTimer()
	at flash.utils::Timer/_timerDispatch()
	at flash.utils::Timer/tick()
This is my function:

Code:
function video_status()
{
	rb_control_bar.status_bar.load_progress_bar.width = rb_control_bar.status_bar.clickable_area.width = rb_ns.bytesLoaded * rb_control_bar.status_bar.load_progress_bar_bg.width / rb_ns.bytesTotal;
	
	rb_control_bar.status_bar.rb_bar.width = rb_control_bar.status_bar.status_bar_scroller.x = rb_ns.time * rb_control_bar.status_bar.load_progress_bar_bg.width / video_duration;
	
	rb_control_bar.status_bar.status_text.text = pad_zero( Math.floor( rb_ns.time / 60) ) + 
				":" + pad_zero( Math.floor( rb_ns.time % 60) ); 
	rb_control_bar.status_bar.dur_text.text = total_min_sec;
}
It is very odd because I have tested this movie externally, independently from the flash document it is currently incorporated into. It woks fine alone, just within the current flash document.
