Hello, I have been doing alot of reading. To get over my problem of trying to create an invoice.
I found that if I run this script in MySQL Query Browser
INSERT INTO material
(Matsubtotal)
SELECT Unit_Price*Quantity
FROM material
where Job_No = 1
It puts the calculated value of the SELECT Unit_Price*Quantity into Matsubtotal field on the materials Table.
If I can do this for all the products in the materials, it not only stores useful information in the database, but, I can now create a custom view with the aid of a join to get all the precalculated fields onto an invoice page, but, When I try it, PHPRunner crashes.
Any help please?
Thanks
Paul.
