Totals in Group Header: need explaining

BenH · March 18

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?

The field <ADOQuery1."Company"> has the company name. Why are we suddenly giving it a new value? Or am I misunderstanding the above line?

<ADOQuery1."Company"> was used as unique value for name of report variaable.
