I have a workbook with 12 worksheets that use the subtotal function to sum up
various sales into a total, operating expenses into a total, personnel
expenses, etc. Different people adjust the input data that makes up the
subtotals, but the equations in the subtotal lines do not change. I've had
problems with people writing over the equations in the subtotal lines instead
of the detail above. I tried just protecting the cells in the subtotal line
and unprotecting the range where people input data, and then I protected the
worksheet using the Tools Menu. But then when I went to expand out the
detail to the next level, it wouldn't let me because of the protection.

Is there any way to protect the cells in the subtotal line while still being
able to toggle back and forth between displaying and hiding the detail rows
for each subtotal? I am using Excel 2003

Thanks
