Summing a field not working.

[cope]

trying to sum a field called calculated downtime based on the date and line ID.
I have the command for the default value of my text box as:



DSum([Data].[Calculated Downtime], "Data", [date of incident] = "date in a textbox in this form" and [LineID] = "Line a")

Keeps returning #NAME.
any suggestions.

[cope]

Tried something different and using this in a query.
Line1DT: DSum([Data].[Calculated Downtime],"Data",[Data].[DATE of Inncident] = [Log times and products].[LogDate])
Says miss an , somewhere.

never seen a date with a value "date in a textbox in this form". Always help if you research how to use the functions - https://support.microsoft.com/en-us/office/dsum-function-08f8450e-3bf6-45e2-936f-386056e61a32

provide the names of your controls in your form that you are referencing.

but I would expect something like

dsum("[calculated downtime]","Data","[date of incident] = #" & format(me.txtDate,"yyyy-mm-dd") & "# and LineID=" & me.txtLineID)

Also no need to prefix the fields with the source name. That is the second parameter in domain functions.

Can't use Me in textbox or query, only in VBA behind form or report.
