[Arp] listening to childs

[Chris Velevitch]

With this type of error, it is usually one of 5 things:-

1. mispelt the event name in the addEventListener call
2. mispelt the event name in the dispatchEvent call
3. in the .fla file, mispelt or omitted the instance name of the child
form in the parent form
4. in the .fla file library, mispelt or omitted the class name in the
symbol properties
5. mispelt the name of the function in either the Delegate call or in
the function definition
