Duplicate Workbook for next month

[scalemo]

I have developed a 3-sheet book to track income, expenses and deductibles for a business venture I am involved in and need to know how to operate it from one month to the next. I need to clear the data from two of the three sheets and retain the formulas built into the sheets which manipulate the data. When I use the clear function under "Edit" it clears data and formula from the selection.

I am using Excel 2003 and have not been able to find instructions on how to do this. I would appreciate any and all help with this.

Excel is a great program, fool around with it long enough and you can figure out anything.
