Sorry, for my tardy response but I have been away. I given up on pivot tables long ago because they are slow and inflexible only one column can be extrapolated at a time. Although there are many different views on the method I now qualify the query instead i.e.
Age180: Sum(IIf(Now()-[Client Sale Date]>180,[Local Amt]-[Local Pay],0))
Age150: Sum(IIf(Now()-[Client Sale Date] Between 150 And 180,[Local Amt]-[Local Pay],0)) etc.
I have a straightforward totalling query. This method was used because I wanted to add Balances using [Foreign Amt] and [Foreign Pay].
It wasn't all that hard and its much faster.
