Sarah, just lock the cells with the formula,

By default all cells in excel are protected or locked, select the cells you
want to unlock and go to format, cells, protection and uncheck locked, then
go to tools, protection, and protect sheet, and depending on want version
you are using if you only want them to select the unlocked cells remove the
tick mark under allow users to select locked cells, enter a password if you
want, now only the cells that you unlocked can be edited, be aware that this
protection is very easy to break, the code to do so can be found very easy,
but it will work for most people .



If you only need a few locked I would select them all first, Ctrl A, then
go to format, cells, protection and uncheck locked, then select the cells
you want to lock and go to format cells and check locked, the go to tools,
protection, and protect sheet, enter a password if you want, now the cells
that you locked can not be edited
