Pivot Table Calculation for Sub Totals

[gmooney]

I have the below pivot table with 2 value columns that I need for any subtotals (in this example Romaine Leaves is the sub total of the 5 rows) to calculate the weighted average of the 5 rows (the math for this is the 3 columns to the right of the pivot table. Instead of 10.9 showing for Average of U/SW the correct answer should be 14.5. The 10.9 is simply the straight average of the 5 rows and that isn't the result that I want.

Any helpers out there?
