Hello

I'm trying to make a report in which I want to print a price that is
calculated from other fields. Is that possible and how?

Regards
Jens
 
On both reports and forms, the Control Source property of a control
determines what is displayed in the control. To show a calculated value, you
just put the calculation in the control source property. This can be a
direct calculation or if it is complex, you can use a function. To use a
function, it has to be preceded with an equal sign. For example, if you had
a function you named CalcPrice, it would be:
=CalcPrice()

You can pass parameters to it as well.
 
Thank you for your answer

I want to use a function like You suggest. If I make a function, how do I
return the value?

My report is from a tabel called post. In this I have fields (itemno,
units). I have an other tabel called items with fields (itemno, itemprice)

My function CalcPrice() must return units * itemprice.

Is this possible?

Regards
Jens
 
Yes, it is possible, but you need to change the record source of your report
to include the other table. You could do it without adding the other table,
but it would be very slow because it would have to do database fetches for
every row.

You do that with a query that joins the two tables on itemno. Then you
don't need a function. All you would need in the control source of the price
would be:

=[units] * [itemprice]
 
Okay I understand about the query.

If I still want to use function, how do I do then. I would like to learn it.

Jens

The function has to be in a standard module.
Then you reference the function as you would a calculated field in your
query. In design view it would be something like:

Price: CalcPrice([units], [itemprice])
