Hey, I have another as3 problem.  
I created a variable:

**var EnergyNumber:Number = 100;**

And I put a buttonMode on a movie clip, which takes away 10 from EnergyNumber when you click it.

\*\*//Action for clicking Girl Button  
Girl\_btn.addEventListener(MouseEvent.CLICK, GirlTalk);  
Girl\_btn.buttonMode = true;

function GirlTalk(event:MouseEvent){  
var EnergyNumber -= 10;  
}\*\*

I also want another movie clip to go to its second frame when EnergyNumber is equal or less than 50.

**function MidDayFunction(){  
if(EnergyNumber \<= 50)  
{ bg\_mc.gotoAndPlay(“MidDay”);  
}  
}**

I was wondering if I went about this the right way or not? I can’t tell if it’s working or not.
