I have a report for Orders, and a subreport for each Order for Invoices.
The subreport shows the total amount for Invoices against each Order.
The Orders are grouped by Area. On the Area header/footer I have an Order
total. I now want to show the total of ALL Invoices by the Order total.
Please can someone tell me as simply as possible how to do this?
For ease I will call my main report ORDERS and my subreport INVOICES.
Any help is greatly appreciated - I have searched through relevant questions
but have not found an expression that works!
