Hello friends, i have problem with my query..
Code:
SELECT tblProduct.type, tblProduct.model AS Model, Count(tblProduct.model) AS qty, tblProduct.cost, [qty]*[cost] AS TotalFROM tblProduct
GROUP BY tblProduct.type, tblProduct.model, tblProduct.cost, [qty]*[cost], tblProduct.buyDate
HAVING (((tblProduct.buyDate) Is Null));
When I run query, will appear popup parameter.. So I think the problem come from QTY... But I just click ok, the result everything is correct.
How if I don`t want popup parameter?
If I don`t use QTY, how I can count the quantity item and multiple the cost by group?
Thanks for help
