Dear Debra,

Could you please help me to solve this problem?

I need to make a 4 quarts rolling chart. The chart data source is from a
Pivot table. Pivot table data source is updated via a link with external data
source.
When External Data Source is updated, a new quarter Q2-07 comes in ,Q2-06
will be out, so there will be always 4 quarts data in the external data
source. Pivot Table Data Source will be updated via a link with External
data.
My problem is every time new colum of quartly data comes in, pivot table is
not showing the new data. I have to manuelly go into pivot table layout, and
drag sum of new quart data into data area.

I have selected Refresh on open in Pivot Table Option.
Could you please help me to make it happen automatically?

Many thanks in advance.
