STAT tag question

[kvdv]

Advanced stats (advanced_stat - version 1.0) - status: ON

Number of all visitors: 518841 -- Number visitors this month: 31829


I know the tag to dsiplay the number of all visitors (<ADVNCD_SITE_VISITORNUMBER>) on my About page,
but what's the tag to display the monthly visitors (i.e. the 31829) ?

thanks!
