In the on format event of the detail section add:

Me!txtSum = Nz(Me!,txtVal1) +  Nz(Me!,txtVal2) +  Nz(Me!,txtVal3)

 

by: AAlpha1Posted on 2009-09-13 at 07:32:01ID: 25320313

Thank you eghtebas:

In the detail section, in design view, there's one bound control and one unbound control calculating the rounded value of the first one. I'm not clear what Me!,txtVal1, Me!,txtVal2, .. refer to

 

by: Helen_FeddemaPosted on 2009-09-13 at 08:03:16ID: 25320452

txtVal1, etc. reference the control names.  Alternately, you can just wrap the control source of the unbound calculated controls in the Sum() function in the controls that do the summing, in the group or report footer.  This technique does not require code.

 

by: eghtebasPosted on 2009-09-13 at 08:37:35ID: 25320589

in

Me!txtSum = Nz(Me!,txtVal1) +  Nz(Me!,txtVal2) +  Nz(Me!,txtVal3)

txtSum is the unbound text box where you want your sum to show.

txtVal1 is the text box where your 1st value is, Likewise
txtVal2 is the text box where your 2nd value is, etc.

To format it you can also use:

 Me!txtSum = Format(Nz(Me!,txtVal1) +  Nz(Me!,txtVal2) +  Nz(Me!,txtVal3) ,"0,000.0#")

for example.

 

by: eghtebasPosted on 2009-09-13 at 08:40:04ID: 25320600

If you have only one text box in the detail section, the use the solution from Helen_Feddema.

Another line of logic would be to create a query and simply drop in the Value you want to rounded twice.
Something like this:

SELECT YourTable.ID, YourTable.YourValue, YourTable.YourValue AS YourValueRounded
FROM YourTable;

This way it is easy to just create the report from the query, and then format the second "Value" field the way you want.
Then simply sum this extra field.
Meaning you don't have to open the report in design view and:
1. Add lots of unbound textboxes into the report one at a time individually
2. Align these controls one at a time individually
3. Format these controls one at a time individually
Oy!
4. But most importantly, you don't have to add the controls together one at a time individually!
You can simply sum the "Rounded" field, like so:
    =Sum(YourRoundedValues)
...in one control, instead of doing this:
    Me!txtSum = Format(Nz(Me!,txtVal1) +  Nz(Me!,txtVal2) +  Nz(Me!,txtVal3) ,"0,000.0#")
(Suppose you had 25 fields to sum?!)
:-O
(Of course you could just open the report in design view and copy the field, if you like.)
I just find it good practice to have the query do all the "Heavy Lifting".

There are many Form and Report Formatting issue that are cleared up by simply doing the formatting in the source query.

Thanks,

But bear in mind that the posts by the previous experts were just as valid as my post.

So you should have really split the points among all the valid solutions.
;-)

I mean, you did say: " Thank you *all* "

There are at least a half dozen way of doing what you are asking.

Please click the "Request Attention" Button and ask that the points be split evenly between all the valid posts.

Jeff,
I'll gladly do that.
I could not get Helen's suggestion to work. I named the calculated unbound control and used the sum function on the named control. It asked for as parameter input. I was hoping for this to work. Your suggestion obviously works.
I would love it if Helen's could elaborate so I can learn what I'm doing wrong.
Again, thanks all.
Albert

Here is a sample of my interpretation of Helen's post.
The Report is called: YourReportHelen

But I don't pretend to speak for Helen.
She certainly does not need me to defend here posts.
;-)
If I am misrepresenting her here, I will gladly yield to her clarifications.

Thank you Jeff,

The sum of the bound field is straightforward. In your example, I modified the report "YourReportHelen" to show what I was hoping to accomplish.

If you can, please take a look.

Thanks again
Albert

 

by: boag2000Posted on 2009-09-14 at 22:27:15ID: 25331938

You have a textbox with a control source of: =Sum([Rounded])
... yet there is no field named "Rounded" so you get a parameter prompt when you open the report.

You can only use =Sum(XXXX)  where XXX is a "Field".
This will not work for textboxes.

So in your case the Control source for both Report Footer Textboxes should be the same.
=Sum([YourValue])

But now I am starting to get confused again.
\O_o/

Again I feel that a even split between all the experts sounds fair, as we all presented valid suggestions in our posts.

;-)
