But I need to know where they got the information for these calculations. So if I look at their excel sheet for net sales it doesn't have a formula in it just some weird folder location. I need to know where they got the numbers for net sales, like where did they get the numbers they input into the formula to get the net sales? I hope that makes sense. I don't understand which numbers from which page they are using to calculate net sales and the rest on the income statement. The excel sheet does not explain where the numbers are coming from for the calculations
