Summing a column in a report

[cinnie]

My report has a column of numbers. Below the column, I would like to show a
text box with the sum of these numbers. In Excel I would just use something
like "= Sum(C3:C56)", but I don't know how to do this in Access. My real
problem is that each report has a different number of rows. Any clues??
Thanks

cinnie,
If you had an uncalculated bound text control named Price, with
numeric values...
= Sum(Price)
would yield the Sum of Price in any Group Footer, or Report Footer.

Use the report footer or a group footer (report footer if you want to sum the
entire report and group footer if you want to subtotal by groups of records)
and add a control to the footer with its control source set to sum the
relevant field. Something Like

ControlSource: =Sum([Amount])

thanks Al and John. I think the reason Control Source: = Sum([txtA])
doesn't work is that txtA is from a XTab query. It is calculated based on a
Count. Does that mean I can't use 'Sum([txtA])' to sum these values? thanks

You can Sum() numeric values from crosstab or other queries. Make sure you
are not attempting to sum in the Page Footer section.

I'm confused why you would name a column/field "txtA" when "txt" is
generally a prefix for either a text box or a field/variable storing a
text/string value.

If it is a text box, you can't Sum() a control.

Yes, that was it! What I had already done was consistent with the good
advice from all of the experts that replied. But still nothing worked. You
identified the key point - that the numbers being summed were derived from an
aggregate function, so the underlying query's field had to be used, not the
report's control. Thanks for a great insight.
