How do you trace inside a movieclip?

[Mr Wabbit]

Personally I wouldnt do it as an onClipEvent.
the var day Im guessing is on the main timeline

I would do:

MC.onEnterFrame = function (){
	if (day < 15) {
		MC.gotoAndStop(1);
	} else if (day >= 15) {
		MC.gotoAndStop(2);
	}
}

This way the statement is checked at the frame rate if you dont need it checked as frequently
Ie, the time of day only progresses from a proceeding function you can set it as its one function to only check when you add 1 to day.

function dayCheck(){
	if (day < 15) {
		MC.gotoAndStop(1);
	} else if (day >= 15) {
		MC.gotoAndStop(2);
	}
}

//Then add the the function to the process
dayCheck();
//if doing this method you will need to place it at the top for your actions frame to check when the frame loads for the first time.

Hope some of this helps you out
