Dear all,
I have a table with some records such as below :

RecType-Step-Fee
1-1-100
1-1-200
1-2-400
2-1-300
2-2-500

I want to show these recordes in a report as below :

RecType:1 and Step:1
-----------
1-1-100
1-1-200
-----------
Sum : 300

RecType:1 and step:2
-----------
1-2-400
-----------
Sum : 400

RecType:2 and Step:1
-----------
2-1-300
-----------
Sum : 300

RecType:2 and Step:2
-----------
2-2-500
-----------
Sum : 500

I put RecType in DataGrouping, Group expression but i don't know how add Step to it.
Can i do this?
Thanks
