sumifs on a pivot table - compare range with range

Hi guys,

I have a pivot table full of sales:
eg:
store, date, sales,type
1,july1,100,sales
2,july1,150,sales
1,july2,100,sales
1,july3,200,sales
2,july2,250,sales


How can I select multiple dates in my sumifs formula:

eg:
SUMIFS(Table_Profit[sales],Table_Profit[store],1,Table_Profit[type],"Sales",Table_Profit[date],(july1,july2))

Obviously I need to replace july1,july2 with code and I could select them from a drop down list.

When I remove the dates in my sumifs formula it will return every sale. I then tried to filter the pivot table with the dates I want but it would still return everything.

Anyone have any ideas
