Shane,

James has a good point.

If you are passing the number of the month, you can modify my simple
function like this:

FUNCTION NumDays
lparameter xmonth
private xdate
xdate=ctod('01/01/'+str(year(date())))
return gomonth(gomonth(xdate,xmonth-1),1)-gomonth(xdate,xmonth-1)

Note that it is important to know which year you are in when using
the function because of the leap years.

:)
