howabout just using this code in your stack script or as an "inserted" script in your message heirarchy


function monthDays paramMonth, paramYear
  # change the numbers to the string version of the month name you are using
  if (paramMonth is among the items of "1,3,5,7,8,10,12") then
    return 31
  else if (paramMonth is among the items of "4,6,9,11") then
    return 30
  else if ((paramYear MOD 400 = 0) OR ((paramYear MOD 100 <> 0) AND (paramYear MOD 4 = 0))) then
    return 29  -- leap year
  else
    return 28
  end if
end monthDays
