Summing a text box on a report

[Dave]

I am trying to creating a cross tab report with price and quantity.

Both price and quantity are read directly from the database. And I can show
the extended price on the report by adding a textbox called txtExtPrice
with the control source as "=[txtQuantity]*[txtPrice]".

But I cannot sum the extended price in the footer as "=sum([txtExtPrice])"
or as "=sum([txtQuantity]*[txtPrice])"

How do I create an aggregate of a computed value on a report?

Your expressions are correct for what you are trying to do. What is showing
up in the text box when you run the report? Are there any error messages? Do
any of the line items result in an error? or in an empty text box?

Thanks Arvin

I am prompted to "Enter Parameter Value" for the name of the control I am
trying to sum (i.e., =sum([txtExtPrice]))

There is a textbox of this name (txtExtPrice) in the Detail section of the
report. Its control source is a computed value; the product of txtQuantity
and txtPrice. I have double checked to ensure I am referencing the correct
name of the control in my sum function.

The txtSumExtPrice is in the footer section of the report. The problem
must have something to do with summing an aggregate because there is
another textbox in the footer whose control source is "quantity" which is a
field value rather than a calculated value and it sums properly.

Thanks for your help. I will continue to look at this.

You can sum a *field in the report's recordsource* - but you cannot sum a
*control on the report*.

If (as I'm guessing) txtExtPrice has an expression as its control source, move
the expression into the report's Query as a calculated field, and sum that.
