Suming values in Pivot Table

[jak82]

Hi,

I have a pivot table like below

	201509 <tbody> </tbody>	201517 <tbody> </tbody>	201527 <tbody> </tbody>	201540 <tbody> </tbody>	201544 <tbody> </tbody>	201546 <tbody> </tbody>	201548 <tbody> </tbody>	201550 <tbody> </tbody>
Agriculture / Pets <tbody> </tbody>
2017 <tbody> </tbody>
January <tbody> </tbody>						10.23 <tbody> </tbody>	10.23 <tbody> </tbody>	11
February <tbody> </tbody>				10.23 <tbody> </tbody>
March <tbody> </tbody>				10.23	10.23	10.23	10.23	10.23

<tbody>
</tbody>

I am wanting to to sum all the values from 201509 to 201550 for March.

How would I go about doing that with Sumproducts?

A single get pivot looks like

=GETPIVOTDATA(GETPIVOTDATA("[Measures].[Sum of InsertNetCost]",$B$5,"[CalendarNew].[Fin Year]","[CalendarNew].[Fin Year].&[2017]","[category].[category]","[category].[category].&[Agriculture / Pets]","[adTrans].[FinWeek Number]","[adTrans].[FinWeek Number].&[2.01603E5]")

Thanks for help
