DSum ! I jumped the Gun

[libraccess]

my earlier post where I had a problem totalling fields on a report I thought the DSum had fixed this
using the =DSum("[SourceVol]","[tblDelMain]") in an unbound control on the report sums all [SourceVol] in the DB
My Report is opened by using two unbound cbo =[Forms]![frmReports]![txtStartDate] and =[Forms]![frmReports]![txtEndDate] via VBAI'm picking I need to either include the DSum in my VBA or in the query for the report to Sum only those records in the report but I cannot get them to work
help again please

How about this in the report footer

=Sum(SourceVol)

[libraccess]

That was my first attempt. The main form has SourceVol as a control with one entry the subform has SupplyVol as control with multiple entries(typ. 1-4 entries). So the report adds one sourcevol amnt for every supplyvol entry
Explanation: SourceVol is a pick up of goods and SupplyVolis thedelivery of goods
So Sum(SourceVol) gives a totally inflatedno. but DSum gives the correct total for all records not the screened records. I am using an Allen Brownecode for screening start enddate and cbo record. Have tried to write dsum with criteria into the vba and also into the query but withno joy
Thanks

Then you can add a criteria to your DSum:

This is what I came up with but it returns an #error
=DSum("[SourceVol]","tblMain","[DelDate] Between #" & [Forms]![frmReports]![txtStartDate] & "# And #" & [Forms]![frmReports]![txtEndDate] & "#")
This I entered into the control source of an unbound control in the Report Footer
I have added a zip that has had some notes highlighted if some could see what is happening here I would be grateful
Thanks

Have you tried with the correct table name?

Brain cramps...we all get them.

I used to do building (houses not DBs) Golden rule, if a plan, when a plan is superseded you file the old one away where no one can get to it. So when you change a tbl name I guess you get rid of any old notes
Thanks again
