I need a function similar to Excel's standard vlookup function where I can lookup a value in cell A1 of Sheet 1 in a range located on Sheet 2 and once it finds a match return a value located in column C on Sheet 2. However, there may be more than one exact match in the range located in Sheet 2 and I want to continue the vlookup loop, each time adding the value in column C of the new line to the first value that was found in order to subtotal all the values in C with the corresponding match value from column A. Any help is greatly appreciated.
