PivotTable - Calculated Field Subtotal

[TheEngineerJoe]

I inserted in a calculated field into a pivot table that multiplies 2 values (this field is titled "sum of Prod Routing Hrs" in the table (see screenshot) and the automatic subtotal on the date (in the row field) will also multiply the values instead of sum them like it does for the other values.  Any ideas on how I can fix this?  I have also included a screenshot of the calculated field.

This is a limitation of calculated fields. Better to either add the calculation next to your source data (if possible) or to use a measure in PowerPivot.
