Hello, I designed a workbook for my co-workers to easily do their expenses and cash out for the customers. I made it multiple ways and allow each person to use it the way they fill comfortable I.e multiple days, single days, etc. All of the sheets link to a totals sheet which has a printable format for the customer. I fear that someone may input data on a non used sheet which will cause a higher total and the person may not realize it. How can I have multiple sheets to pick from all linking to a master total sheet but if data is filled in from multiple sheets it will either let the user know or only pull from the sheet they are filling out? If a sample needs to uploaded let me know and I will upload the copy I made.
