Hello everyone. I need help please. I have a couple of checkboxes on my stage. The checkboxes(when checked) should add a number to a dynamic text box on the stage. This text box has a variable name “lblmaintotal”.  
Is this possible?

Here is the code I used:

var lblmaintotal:Number;

lblmaintotal = 96908;

MPListener = new Object();  
MPListener.click = function (){  
if(MP.selected){  
lblmaintotal = lblmaintotal + 2290;  
}  
else{  
lblmaintotal = lblmaintotal;  
}  
}
