Denis,

I looked at several reports I have created with Stonefield and the Group By is the only explanation I currently have. Can you give some more detail please?

What is the select statement for the DoQuery?

If you Edit the report, on Step 4 (Standard Sort Options) what fields do you see, what ones are missing?

Kind Regards,

Mat
