[ic] Is "delete_shipping" working?

[interchange-users@icdevgroup.org (Interchange User)]

I found this code from the simple demo for deleting a shipping 
address.  I tested and it is not working, may I know whether 
"delete_shipping" is working, or if this is the right way to call it? 
 If not, how can I achieve this deletion?


[set [L]DELETE shipping[/L]]
mv_todo=return
mv_nextpage=ord/checkout_mv
[userdb function=delete_shipping]
[/set]

You can recall a shipping address from your address book.<BR>
[loop arg="[value address_book]" ]
<INPUT TYPE=checkbox NAME="s_nickname" VALUE="[loop-code]"> 
[loop-code]
[/loop]
<INPUT TYPE=submit NAME="mv_check" VALUE="[L]Recall shipping[/L]">
