Help needed with shared object :-(

Situation:
After reading Shared Object Turotial on kirupa.com i want to store a file
name in a shared object, then open a new window, and retrieve this file name.
I try to use this to read/write comments on a weblog.

To set up the sahred object i use this code on a button:

on (release) {
//save comments_file name in a shared object
user = SharedObject.getLocal(“fechacomentario”);
user.data.entrada = “http://xxxxxxxxxxxxxxxxxxxxxxxx.txt”;
user.flush();
//open comments windows
_level0.getURL(“javascript:contacto(’…/diario/comentarios.htm’)”);
}

And in the new window y put this on a keyframe:

//load shared object
user2 = SharedObject.getLocal(“fechacomentario”);
entrada = user2.data.entrada;

then i’d use ‘fechacomentario’ to load a dinamyc text, but it seems not
to work.

Any suggestions? Thanks!
