Excel2003 ... Pivot Table & Chart working fine ... (Excel Range A1:P40000)

Above said ... I repopulated Table Source Range with new data (4 pns only
instead of many) ... then I "Refreshed Data" ... Table appears fine ...

Issue ... All the drop-down Filter Switches still contain the many pns from
the previous data instead of the 4 I only wish to see now ... Same holds for
the other Cols as well (Table looks fine ... But Filter drop-downs are
showing old data)???

How do I get the drop-downs to "Refresh"? ... Thanks ... Kha
