Hey, I'm new to flex, literally just started yesterday... Anyway, a friend ask me to make him a calculator for a service he plans to provide... I was doing fine until I decided to place the options into an accordion, now I receive a runtime error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

at mx.controls::Button/mouseUpHandler()[E:\dev\3.0.x\frameworks\projects\framework\src\mx\ controls\Button.as:2765]
The code works perfectly fine when I take the elements that call the updateTotal function (calculates the cost and updates text...)... Also, if I move to the 2nd accordion canvas, everything begins to work fine (even on the 1st canvas when I switch back to it...).
Thanks
