I think you missed this bit of the OP:

The values displayed in the list box are being changed dynamically via JavaScript.

Your code will return the initial contents of the list box, not the content changed by JavaScript as desired by the OP.

(By the way, why are you're using a hidden field and not the session to send data from the script to a future invocation of itself?)
