How make largest calculated value in detail section of report print in footer section

I have a report that has a calculated number value in each record on the report.  In the footer section of the report I want to print the largest of the detail values.  Just the one largest value.  How can I do this?

Assuming the calculation in the the query driving the report, create a text box in the Footer

you can try dmax with a domain


"queryName" is the name of the Record Source of the report

The first suggestion does not work.  The second one only gives me the last calculated value from the detail section.

And actually, make the Control Source of the text box


not DMax()

And using the method will take into account any filtering that may occur when the report open.  Getting DMax() from the query will not.

is this a continuous form, or a single form?

It's a report ...
Me being me, I'd code it

Public TheBiggest as Single 'or double or integer or whatever

Then in the ReportOpen()

Then in the Detail_Format()
if WhateverYouAreCalculating > TheBiggest then
     TheBiggest = WhateverYouAreCalculating
end if  

And finally in whatever section you want to display it
Me.SomeControlValue = TheBiggest

You might be able to muck with some control value to get it to work--and that might be more elegant.
This will work, and you can understand how it works--which is why I'd do it this way
