lists
 

How can I protect a worksheet so that people can not destroy the formulas in
certain cells but make it so the list still activates?

lists
 

I have created excel lists. Within these lists I have cells with formulas,
these formulas in columns G through T corespond to the data typed into
columns A through F. I need the list to expand because I don't know how many
sources I am going to have per list. How can I protect the sheet so that the
formulas will not get damaged but still have the lists activate and expand?
