Aggregating Custom Calculated Field in Reporting

We use a custom calculated field to show the difference between planned and actual expenses. This rolls into reporting for each expense just fine, but I'm tripping over myself on the aggregation. The text mode I've set up for this on the View for this custom calculated field is: aggregator.displayformat=currencyStringCurrency aggregator.function=SUM aggregator.valuefield=PDS | Expense Difference aggregator.valueformat=doubleAsDouble displayname=Expense Difference linkedname=direct namekey=PDS | Expense Difference querysort=DE:PDS | Expense Difference textmode=true valuefield=PDS | Expense Difference valueformat=customNumberAsCurrencyStringCurrency Any ideas?
