Hi,
I have an excel sheet with lots of formulae in it. The value in column C
will change when the value in Column A changes (Col C has the formula). I
dont want the user to edit Col C and so i have locked C and protected the
sheet. But the user can edit Col A. When Col A is changed i am unprotecting
the sheet, calculating Col C formula(Might also insert new rows based on Col
A) and then again protecting it ( all through code) .But sometimes this code
gives me #Value error in Col C when Col A changes. Any solution for this?

Thanks.
