I am trying to create an annual spreadsheet where in column "A" I have the date, in column "B" I have an assorted array of 9 machines and in column "C" I have the time accumulated on the machine. What I am trying to do is;
Each time a certain machine is used in the different months I want the time accumulated in "C" to be added together in a separate column
I hope there is someone out there that understands my problem and can help
