Copy Worksheet while keeping incremental formulas

[winchwrench]

In my workbook, I am calculating the collection of oil and water on an hourly basis and subtotaling on a 24 hr basis for several days/weeks in a row. I need the subsequent sheets after the first 24hr sheet to continue their formula and 'carry over' the previous sheets data. I've done this manually for a 21 day period, but am frustrated b/c I dont know the formula. Now, I want to make some minor changes & would need to possibly redo the subsequent sheets. AAArrrggghhh. Can anyone help me? I'd be glad to share the doc. Thank you!
