Hi, I'm trying to get a total inventory count with multiple batches. On Sheet1 I'm trying to get a total count of Column A in Column D. Using Sheet2 as the data the parts can count multiple times in column A. I want to take the values in Column D and add them up if the value in column A is the same to present in Column D of Sheet1. I tried to use Index/Match but that won't count the multiple lines.
