Pass values with Shared Object

Hello. I am trying to send some values to a swf to another swf file with shared object. I use an example from the internet but nothing happens with my swf files. The idea is that I have a couple of swf files that perform some actions and then on a click I have to pass some values to a main swf file. It is like a stack that in which I have to push data and delete data. Here is my example that is not working, does anyone can help me ?
Thank you.
