Hi,

I have been changing a bunch of reports to get data from last month

formula:

@firstdaylastmonth : dateserial(year(currentdate),month(currentdate)-1,1)

@lastdaylastmonth : date(year(currentdate),month(currentdate,1)-1

Works perfect in the first ten reports, in the eleventh report :
firstdaylastmonth = 01/05/2006 and lastdaylastmonth = 31/05/2006

?????????

How does that happen ?

thanks
