Grahamfff   10 #1 Posted August 16, 2019 I need to group the date in an access report. The underlying data is from a query, rather than a table.  When in design mode, I click to group the data and select the field to group by but Access gives me the error sign ( a little green arrow) which, if I click it, tells me there's a grouping error. However, when I click to view the report, it appears to be correct.  What could the error message mean?   Share this post Link to post Share on other sites Share this content via...
