Global NumberVar Tier1;
Global NumberVar Tier2;
Select {yourtable.payment} 
Case 1000 To_ 2000:
    Tier1 := Tier1 + 1
Case 2000 To_ 3000:
    Tier2 := Tier2 + 1;
;

This tracks how many people are in each tier and stores it in global variables. The problem is that you only put this at the end of the report because it is a manual running total and only does the calculations as the report runs. So to put it in the header, step 2 would be to create a subreport that uses the same data as the main report and includes this formula. Then you can print the values in the subreport and include the subreport in the main report's header. A little tricky. but perfectly doable.
