We have two different workbooks (Master & Slave) both the workbooks have one unique column i.e ID. Slave workbook has duplicates ID along with Amount figure. We want to get the sum total of those duplicates ID's amount and single entry amount should also be reflected on our Master workbook amount column.
eg
Slave Workbook
ID Amount
766 800
566 900
766 1000
675 200
566 100
Master Workbook
ID Amount
766
566
675
eg

566 900
766 1000
675 200
566 100
Master Workbook
