You regularly wouldn't run across this error.
I have a report with several groups - and a Total field thats an Invoice Amount.
In the Group, you set the Evaluation Details to calc the total in each of your group bands.
All is fine up til now.
THEN, I wanted to hide the totals when basic users ran the report. So I attached a condition for AccessLevel='Manager'.
the problem is the "Evaluation Details" section now is missing on a conditional tag.
So the Total, which was set to calculate for the group now became a Running Total.
Sure, it was hidden correctly when the user was NOT a Manager, but for Manager, the report totals were all messed up compared to the version before the conditions.
Like I said, this is a weird error thats only going to show up when using a condition on a SUM-type field IN A GROUP.
But my only option now is to duplicate the entire report for non-Managers and physically drop the field (I HATE redundancy and duplicate code).
