Crystal Reports Creating month bucket array

Message

     Hi All,

I have to get database info from the first month of the year (parameter date) till the month of the date (parameter date).

for example, if parameter date = today (2011-07-16) then report should be:

                    db_info_01        db_info_02        db info_03 
2011-01-31
2011-02-28
2011-03-31
2011-04-40
...
2011-07-16

Could someone tell me how to create this kind of bucket array (max. 12 bucket)?

thanks in advance,
