I have a worksheet where Column D is a list of vendor names (column named "VendorName"). In Column D, the vendorname could take up multiple rows -- so, for example, one vendor named "Seale" takes up rows D2:D9. I need to sum up the totals of the vendors, but given that my XLS is 10,000 rows I can't manually go through and add. I know I could do a Pivot Table and get the totals but vendor name, but there is another hitch. In Column U (named "LineItemAmount") there is the positive debit and in Column V (named "AdjustedAmount") there is the negative credit. I need to sum up the two of these to get the total, based on the vendor name in Column W. Please advise! Answer as soon as possible would be great.
