About aggregate fields trouble (Delphi 7.0):
1. create my TMyQuery
2. create aggregate field
3. write to expression sum(qty) (qty is filed with quanity)
4. set property active to true
5. create DBText and assing it to aggregate field to read value
6. run application
7. when open query DBText not show sum(qty) value. They are also empty. Application run, but aggregate field don't calculate.

May I do some wrong?

Hope above help you to find a problem !

Can you get a value of the field through MyQuery.Fields[].AsString?
Can this value be displied in DBGrid?
Please specify script to create tables and text of the query.
