I'm really new to the report builder, so forgive me for my lack of knowledge on report dev jargon Confused

What I need to know is how do I take a value from one field, multiply with a value from another field and put the result in (yet) another field?

This is for my uni project, and it's the only thing I'm stuck on Embarassed

Thanks in advance!

PS: I'm sorry if there is already a question like this, I just wasn't sure what to put in the search Laughing

Two ways I can think of at the moment.

The first one is obvious - multiply those values directly in a query:

SELECT unit_price, quantity, unit_price * quantity service_price
FROM some_table
WHERE ...

Another one is to use a formula column. It is a function that returns a value (number in your case); its body would look like

RETURN (:unit_price * :quantity);

Note colon signs which mean "reference this value from the column I've already selected".
