I have an interesting issue. I wrote a simple update query that uses a dsum formula and it worked fine in access 2007. my computer was recently upgraded to access 2010 and the query no longer does the right calculations. There are no errors, just blank cells and false results.
The query only calls one table, named PreSum. It updates one field in PreSum called Paid Cumuler.
Here is the code:
UPDATE PreSum SET PreSum.[Paid Cumuler] = DSum("[Paid]","PreSum","[ClaimNb] = " & [ClaimNb] & "AND [Treaty] = '" & [Treaty] & "' AND [Section] = '" & [Section] & "' AND [Line of Business] = '" & [Line of Business] & "' AND [Invoice Date] <= # " & [Invoice Date] & "#");
All fields are in the table PreSum
As I said, there are no errors and it works in access 2007.
Thanks
