Could you please help me?... I locked and protected the cells A1:H20 in the
sheet 1 two months ago. However, yesterday I wanted to unlock and unprotect
these cells and locked and protected the cells A21:H40 instead. However, for
some reason the cells A1:H20 are still lock and protect.
How can I remove the previous lock cells (A1:H20) and keep the new cells
(A21`:H40) only.

Thanks.
