The referenced dataItem was not found at the same nesting level

[bhassel]

I built a crosstab report that breaks down data by years.  It looks like this:

List:  Fiscal Year
Xtab: 
                                                             | Label | Total $'s |
Service Code | Service Code Description |          |               |
Totals                                                    |          |               |

Now I want a further breakdown by quarters (data set/query includes quarters column).  However when I attempt to just add Quarters to the left side of the crosstab (left of Service Code) I receive the error, 'The referenced dataItem="Svc_Cd" was not found at the same nesting level.

I'm not sure what the error is telling me I need to do.
