Hi,
I’m new to AS3 and flash but I managed to learn from alot of reading. I have some code uploaded at this link: http://www.chuayou.com/pages/programs.htm but I’m getting an error. Namely this is the error I’m receiving:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.events::TimerEvent@70180b1 to flash.utils.Timer.
at flash.utils::Timer/flash.utils:Timer::_timerDispatch()

This is the code for the main class that I’m using:

I know this is a TON of code to look over, but can anyone please help me! Its incredibly [COLOR=“DarkRed”]URGENT[/COLOR] that I resolve this ASAP!
