    Hi,

    The criteria concatenation in

    DSum("Amount","tblDrawsDetails","FacIDfk=" & [FacIDfk] And [ID]<=[ID])) AS RunningSum

    should be

    DSum("Amount","tblDrawsDetails","FacIDfk=" & [FacIDfk] & " And ID<=" & [ID])) AS RunningSum

     

    Servus

ahh I  had the quotes messed up.  I didnt notice that.  

 

It worked perfectly.  

I did end up basing it on a date instead of an ID:

RunningSumDate: DSum("Amount","tblDrawsDetails","FacIDfk=" & [FacIDfk] & " And nz([DateRecd],0) <=" & Format$(Nz([DateRecd],0),"\#mm\/dd\/yyyy\#"))

    you can't use DSum() on your RunningSum because:

    1. there are ID that have big ID yet earlier date (maybe late entry?)
    2. there are dates that fall on the same date (facIDfk = 3 , sep-26-2023, 3 records).

     

    so your last hope is the function i provided.

      Hi Arnel,

      Yes, you are correct with your points above.  

      I dont think #2 is as concerning though since I think <= on [DateRecd] would capture those records where they are on the same dates.  

      Could the function be revised to base it on the [DateRecd] instead of the [ID]?  If too time consuming I can use the Dsum since it does work.  

      RunningSum: DSum("Amount","tblDrawsDetails","FacIDfk=" & [FacIDfk] & " And nz([DateRecd],0) <=" & Format$(Nz([DateRecd],0),"\#mm\/dd\/yyyy\#"))

      thank you sir!

        or a combination of date and ID.

         

        try your suggestion and you will see that the second record has RunningTotal, the same as it's amount (30,700,000.00) when the RunningTotal should be, up to that record, 36,393,629.74.
