two steps:

1) For the cells where you want to lock and hide the formula
Do Format Cells Protection choose locked and hidden
For other cells where you will input data, which will not be locked, choose
unlocked and unhidden

2) do tools protect worksheet. choose the actions you want the user to be
able to do.
