Error in simple Tutorial? With(object) gives undifined..

Question

Hello, I got this from an tutorial, but when i run this
the
trace(person1.address.street);
gives undifined ? How come this is undifined and
trace(person1.address.test);
is not? ..looks like the With( ...) does not work?
here is the script:
person1 = new Object();
person1.address = new Object();
person1.address.test = "hello";
with(person1.address) {
street = "123 Main Street";
city = "Boston";
state = "MA";
zip = "02114"; }
trace(person1.address.street);
trace(person1.address.test);

Answer 1

"To set a variable inside a with statement, you must have
declared the variable outside the with statement, or you must enter
the full path to the Timeline on which you want the variable to
live. If you set a variable in a with statement without declaring
it, the with statement will look for the value according to the
scope chain. If the variable doesn't already exist, the new value
will be set on the Timeline from which the with statement was
called."
ie, street is defined on the timeline that contains that
code.
