Facebook High Score

I know a lot has been asked about this, but the problem I am facing is not the same as anyone else I have seen. I think I am doing something simple wrong. Here's what the event looks like:

What I am seeing is that there is always just one entry in the listbox.

Shouldn't the event trigger for each high score, and add a new item to the list?

Thank you.

This is the game over screen.

I can't figure out what's going on here. The script may be okay after all, but the exported content is not updating. The reason I know this is because I changed the listbox to a text file, but it still has the listbox on there after many exports now.
