GetVariable() doesn't work in FireFox for object member variables

Question

I'm trying to access Flash member variables from Javascript
using GetVariable. The following line of code works for IE but not
for Firefox:
var variable = swf.GetVariable("someObject.someProperty");
In IE, the GetVariable() function returns the correct value
for the property. However in Firefox, the GetVariable() function
returns "null" when trying to access the property. If I just try to
access the object in Firefox (i.e. swf.GetVariable("someObject"), I
get a string back (instead of the object that I am expecting). If I
try to access a variable (such as a string) and not an object using
GetVariable(), this works in both Firefox and IE.
Any ideas what I am doing wrong? I suspect that my syntax for
accessing object member variables in Firefox is incorrect but I
have not been able to find any documentation on the correct syntax.
Any assistance would be greatly appreciated.
Thanks.

Thanks, but this isn't an issue.
The window.document.flashMovie will return the correct flash
object/embed flash movie.
The issue is that the GetVariable method wont return the
object variable. When you try to get an simple variable that is in
the _root timeline, it will return the value. Example:
movie.GetVariable(_url) will return the url of the flash
movie without any problem.
But when you create an ActionScript class with
userName property and then you will create the instance of
it in the _root, you should be able to get it's value. Example:
Flash:
var obj = new SomeClass();
obj.userName = "peter";
JavaScript:
movie.GetVariable("/obj:userName");
or
movie.GetVariable("obj.userName");
This will return
Peter for IE and null for Forefox/Opera.
The same when you use the document.embeds[..].
