How to display the available download left for HotSpot users

Hi,
Does anyone know how to display the available download left for the HotSpot users upon login? The “status.html” page only shows the available time left. I tried to modify the html tags without success.

such further functions would be very good. A disclosure of further variables except that available $(ip), $(bytes-in-nice), $(bytes-out-nice),$(uptime), $(session-time-left), $(uptime), $(refresh-timeout) would be very helpful

sorry for my English…

Yes, they would VERY helpful. Help anyone???

found it: $(remain-bytes-out)
