hi can anyone help me on this,im having a little trouble about the group sub report, what i need to do is to change the value of a variable depending on the group sub..

an example is like this:

i have a report that is group by name,when i grouped that report, it ranges from 1 to 6 pages per record,now the grouped field only shows on the first page,what i need to do is on that first page, a variable has  value,lets say its "1",then when it goes to the next page,the variable becomes "2",then just repeat the changing of variable for every record...can this be done?hope you understand what im trying to say,thanks in advance though
