What you are trying to do in Assignment $6$ is to have VBA calculate Monthly Sales for each of the $5$ Sellers that are in cells I$6$:I$10.$ Furthermore, you will calculate the TOTAL sales in cell I$11.$ Your approach should adapt to the size of the data in this sales sheet. In other words, there are $11$ rows shown in the data here $($and in the starter file$),$ yet your sub should work the same if we had $20$ rows, for example, or $50$ rows. The format of this sheet will always be the same $($headers will be in row $5).$

Next, you need to have VBA automatically calculate the Total Boxes of each of the $3$ different cookies in cells I$14$:I$16.$ The attached file is what it is supposed to be$.$ Initially they're all blank. I can't figure out how to code this. Is there an easy loop that I$\text{'}$m not understanding?
