Header Can Not Use Footer Data

[Robert_DubYa]

I have a field in a footer that is simply just a total by day. In a header
I'm wanting to sum this data by week. When I run the report I get a prompt
to input the data. I'm sure this can be overcome, but I just can't figure it
out.

thanks,
Robert

Which "footer" and which "header"? Are you grouping by days and weeks? You
can't sum controls across sections. You can sum fields or expressions from
the report's record source.
