How do I create a drill down for my summary data?

I have 7 fields of summary data with all having a common link called the customer account number.

I have tried the following steps several time carefully and was unable to get my drill down to work.

Insert menu > Group and chose the customer account number as my group field

copy and paste the summary fields to the group header ( which I now have hundreds of GH1)

Right click on the details section and chose Hide.

Suppress the Group Footer

File Menu > Report options and check on Show All Headers on Drill Down.

I must be missing a step somewhere here.  I end up with no summary fields showing (to drill down into), and the customer account numbers showing.

Can some check this out for me?
