Totals in Group Header: need explaining
Posting this also under Fastreport VCL in case the group Fastreport 4.0 was the wrong group:
So a while back I came across this video explaining how to add group totals to group header.

At one point the uploader puts 2 OnbeforePrint events.
In the second event he writes the line
Set(<ADOQuery1."Company">, Sum(<ADOQuery1."ItemsTotal">, MasterData1));
The field <ADOQuery1."Company"> has the company name. Why are we suddenly giving it a new value? Or am I misunderstanding the above line?
In the first event he writes
Memo3.Text:='Sum:'+FloatToStr(Get(<ADOQuery1."Company">));
If Memo2 already contains the sum, why not just write Memo3.Text:=Memo2.Text?
