I've picked up this book and so far it looks good. I have downloaded a few of the samples of code and some don't work or give an error message.

TooEarlyExample gives me an error message of;

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at TooEarlyExample()

The flash file has two text fields and the code is supposed to populate them with some text. The first text field doesn't get populated with text but the second one does.
