Sum (Aggregate) subquery using fields in query as criteria

Hello - I'm trying to put together an Access 2016 query that has a field that calculates an aggregate Sum, dependent on a subset of date in that same query. After multiple subqueries, separate queries, and even using a report date field in a row to key off of, the date criteria does not use the date in the query and rather uses the entire year, which is the hard coded criteria in the query.

I'm open to any approach to basically use a date range defined in fields in the query, in order to be used as a subquery's criteria. More specifically, and using the output and code attached, we need to use the dates in INV_APP_DATE and TWO_COM_RECIPIENT_ID as parameters for the subquery that totals up INV_APP_AMOUNT * TWO_COM_CREDIT, in the field NetCredited. There is a hard coded parameter of dates using only 2017. So if the date in INV_APP_DATE is 4/1/2017, then the total of INV_APP_AMOUNT * TWO_COM_CREDIT should include all records from 1/1/2017 to 4/1/2017. But instead, the total reflects ALL records in 2017, which is the 6765739 seen in the screen shot. It's as if the specific parameter on INV_APP_DATE isn't used, no matter how it's coded.

Attached is a screenshot and the SQL as well. Any ideas would be great.

This would be alot easier to help with if you could provide a sample of the database, just with the table itself, and the query you are trying to modify.

Are you sure that's the total for 2017 and not for 2017 and prior years? The date filter in the subquery just says where the date is less than or equal to INV_LINE_APPLICATIONS.INV_APP_DATE:

         ... AND REPCOM_SUB.INV_APP_DATE <= INV_LINE_APPLICATIONS.INV_APP_DATE

 If it must also be in 2017 only, you must to specify that in the subquery too.

hi. I am not an expert but i guess wrong results may appear if correct date format is not used.

e.g. Format(Me.PoDateFrom.Value, "YYYY\/mm\/dd").
We are using DD/MM/YYYY format

Thank you everyone. Here's a quick response to all posts, and I apologize for the delay. Been caught up in some priority fire drills at my business.

To Anders - Yes, maybe I can do that after this next round. I haven't so far, as there are multiple tables and they are big.
To agx - The reason why it doesn't bring in years prior to 2017 is that there's another query parameter hard-coding the year as 2017. But this does make me wonder if that other parameter might be overriding the sub-query.
To Kamlesh - yes, I've used date formats (#17/04/2004#) with no success, but haven't used the exact same syntax as you write. You're basically changing the format or sequencing of years, months, days. Don't know why this would change anything but will give it a try.

If anyone has any other ideas, please let me know. Otherwise, I will try to get a sample DB posted. Thanks.

Hello - I'm closing this out. In the process of setting up a test db, I found out that it was the combination of a hard coded parameter and the date range parameters (hard coded over-rode the date range). So it will be a pretty quick solution at this point. Thanks for all the comments.

As the last comment indicates - the problem was the combination of a hard coded query parameter taking precedence over a date range parameter.
