I'm running the configuration for a readial guage.

I'm connected to a SharePoint list with 24 items. I can connect and preview my data.

Each item has a column called "Value" and I want my pointer to point to the sum of the column values.

On the Guage | Guage Areas | Pointers | General tab, I'm using the formula:

     =SUM(Fields!Actual_Value)

When I try to preview, I get:

     Gauge Preview Failed: Pivot processing failed during: Phase: Processing Pivot - Filtering. Error was: String was not recognized as a valid Boolean.

What string am I missing?
