Suppress If Duplicated On Group Label

Question

I'm using Crystal Reports 2008
I have a report that is to display just the totals (not the details) for each group.  To that end, I put the fields to be totaled in the detail line and used Insert Summary to create the total fields for each group (there are two groups).  I then hid the detail section, as well as the Group Footer sections (1 & 2).  Finally I dropped the group field names into the Group Header 2 line.  It works well, but I get the same Group 1 field repeated for each item in Group 2.  Sort of like this:
Group 1
Group 2
Total 1
Total 2
0008
Section A01
123
234
0008
Section A02
53
245
0008
Section A03
152
453
0010
Section A01
34
112
I'd like to have the 0008(number) label (in the example above) be suppressed if duplicated, sort of like this:
Group 1
Group 2
Total 1
Total 2
0008
Section A01
123
234
Section A02
53
245
Section A03
152
453
0010
Section A01
34
112
I tried the "Format Field" option and selecting "Suppress If Duplicated", but that did not seem to have an effect.
Thanks!

Sorry, change the code to:
WhilePrintingRecords;
numbervar array arr;
numbervar x;
if not({Group_Name} in arr) then
    x := x + 1;
    redim preserve arr[x];
    arr[x] := {Group_Name}
else
0;
