Running sum in query

[chavez_sea]

Good day,
I have a form that calculates running sum when inputting data into a cash account table. There is an expenditure , and a deposit column, and I would like to run a query that would give me the running sum also, so I can run a report showing the entire cash book with running balance. There is a Autonumber field to keep record of the transactions. THis is what I have in the running sum field on the form : RunSum([Form],"Payment FIle No",[Payment FIle No],"Deposit")-RunSum([Form],"Payment FIle No",[Payment FIle No],"Amount")
Any help or alternative method would be appreciated.

Thanks Cristina

So you have custom functions that do the running sum on form - did you try these in query?

Report textbox has RunningSum property. That's the easiest approach for what you want.

That code was given to me. I dont know to write it. When I put that in the query it shows up an error.
Can you give me detail instructions.

Thanks

I don't know purpose of argument for which the [Form] parameter is provided. Would have to see the function code. Suggest you instead explore the RunningSum property.

The purpose of the code in the form is to show the cash balance after the expenditure transaction. WOuld I please be allowed to send a copy of the dbase.
Thanks

Running sum is not simple in form and query. A total at bottom is easy.

One method for running sum using DSum https://support.microsoft.com/en-us/kb/290136 - be aware domain aggregates can perform slowly.

Do web search for more info.
