NC,
I am confused by your use of text box and field. A field is a column in a table or query. A text box is a control on a form or report.
You can't sum a control from one section of a report to another. For instance if you have a text box in the detail section of your report:
Name: txtTotalCost
Control Source: =[Qty] * [Price]
You can't add a text box in any header or footer with a control source of:
=Sum(txtTotalCost)
You can set the control source to:
=Sum([Qty] * [Price])
BTW: [blue]Value[/blue] is not a good name for either a field or a control. [blue]Value[/blue] is a property of most bound controls and other objects.
