I've been trying to get the DSum function to work but I've been running into some roadblocks. What I'm trying to do is to total up times in a timesheet report into different departments. The report is based on a query that gathers all an employee's info. In that query, I have a calculated field which gives an employee's total time on a process.
(DateDiff("n",[StartTime],[EndTime]))/60
This gives the total time in hourly fractions. Now what I'm trying to do on thre report is to total up these times but also to divide them up between which departments they belong to based on a process code. Here's where I'm running into issues. This is the Dsum functon I've been putting in the Control Source for a TextBox:
=DSum("[Time]","TimesheetQue ry","[Process#] >= 3000 And [Process#] <=3501")
This is only one variation that I have used. I'm really more of a beginner with Access and am learning through trial and error. As I've been looking at different threads trying to see what might make this work, I've tried several other variations but nothing seems to come out right.
Is it because I'm trying to sum a calculated field? Is it because I'm using the function incorrectly or entering it wrong? When I go to the report I'm getting '#Error'. Thanks again for the help

I seldom use this kind of thing in my practice, but I think you've diagnosed your own problem! As best I can remember, in order to use Aggregate functions, such as DSum(), with calculated fields, you have to include the calculation expression itself, rather than just a field that holds the results of the calculation.
Also, you probably need to change the name of Process#. The # sign is used by Access to delimit dates, so a statement such as
=DSum("[Time]","TimesheetQue ry","[Process#] >= 3000 And [Process#] <=3501")
is apt to confuse the Access gnomes making them think that everything between the #'s is a date!

Ok, so I tried putting this in
=DSum("DateDiff ("n",[StartTime],[EndTime]","TimesheetQue ry","[ProcessNumber] >= 3000 And [ProcessNumber]<= 3500")
and received the error
The expression you entered contains invalid syntax
You may have entered an operand without an operator
Any advice?
Hey thanks again for the time and help missinglinq but I found a different way around the isssues by using IIF statements in the query.
Have a good one!
Glad you got it working!

I'm using Access 97 and need some assistance in sorting out a proper
DSum expression, or maybe even DCount might be an alternative. I have
tried numerous combinations, but with no apparent success.
The DSum function relates to a subform (sfrmCost) with a text box
(RefCost) which is intended to be the container for a total from a
query (qryItems). The query has three number columns from the table
(tblItems) of which I have an expression...

This seems a bit odd, but I have not been able to persuade Access 97
to format several DSum total columns in Currency - Standard format. It
appears to be defaulting to a general number format instead. The text
box format is set to standard and so is the related query properties
supplying the totals.
Does anyone have any ideas as to a workaround for this issue?
Thanks, Dalan

Hi,
I have the following in my query which works well if it is all set to
numbers on table design.
But what I want to do is where it states MC (short for machine name) use the
actual machine name of which there are 5 off. therefore, on the table design
I flick it over to text mode.

I have never used this function before and am not sure it what I need.
Just to clarify, I have a report based on a query which has amoungst other

for the main report which gives a generalised breakdown of the main report.
For the gender of 'Ladies', there may be several parea's so I want to sum
the packs_req for ladies only. (Gender is not a field I can use,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
