Hello Peter 

You are supposed to call FSSession only once which initializes it for the 
whole transaction. Just don't call it again in 'standard_html_footer'. 
FSsession commits its data at the end of the transaction. By calling it 
again in 'standard_html_footer' you force it to reread its data before it 
had the chance to commit its old state. 

Let me know if it works. Maybe I should ignore additional calls to FSSession 
if they occur in the same transaction.
