Dear Forum

I need some help with a summary field, the situation here is that I have a normal portal with fields in it. This fields are the typical fields to make an order in a POS system, 1. quantity 2. unit price 3. total price

quantity field * unit price = total price

at the end I have a summary field that gives me a total of the total price for my ticket, everything is ok, but the problems is that if I change the quantity field with a pop up list from 1 to 5 for example the changes are not visible in the summary field at the moment just when I change to another layout. The summary field is outside of the portal.

Anyone knows how to make active the summary field in order to work and calculate right at the moment when the quantity field is changed at any time, this is causing me serious problems. I don`t know if a I have to change something in the summary field or the total price field that is a calculation field. help?

Thanks

I think that you should change the summary field to a calc field in the parent record that uses sum( ). Maybe this demo will help: Invoice Demo

I don´t know if is it correct but I tried sum() funtion but only works for the first line of the portal not all the records in the portal, any help or any other solution that someone has???

or maybe I´m not using correctly the sum() funtion.

Thanks

"I have a normal portal with fields in it" --really?

Do you have two tables, one for the Sale and one for the Sale Line Items? Are they related by SaleID?

Look at this demo file: Invoice Demo
