Need help to use Two Slicer for filtering pivot Table

[spycein]

Hi Everyone... Need your help again.. I have two pivot tables and i have created two slicers and connected with both the pivot table..

PivotTable1:-
Filter
Month
Invoice No.

Rows Column
Dates Values

PivotTable2:-
Filter
Month
Invoice No.

Rows Column
Dates spot Counts

And the slicers are:-

Slicer 1 Name:- Invoice No. and Slicer 2 Name:-Month

Now if select the invoice no. in the slicer 1 the both the pivot table shows the invoices for the overall month and if i select the month in the slicer 2 then both pivot report show month wise value.

What i want is to get the pivot report month & invoice wise. For example if invoice no.1 is entered in April 2014, Invoice No.2 & invoice 3 are entered in May 2014 and if select May in the slicer 2 then in both the pivot report invoice 2 & 3 should be shown.And if i select April then Invoice no.1 should be shown only.

Hope you understand my query...

Again thank you so much for your help...
