Row Numbers for Group

I have a table with 2 Groups and I want to number only Group2 with row
numbers. I put in a RowNumber(Nothing) function, and i'm getting something
like this:
Group 1
11 Group 2
14 Group 2
28 Group 2
Group 1
35 Group 2
etc...
What can I do to get the numbers to show up correctly?
Thanks!problem solved!
