Hi there,

Here is what I'm trying to accomplish and can't seem to solve:

If I enter a time value such as "3:00 am" in cell A1, then 24 hours (or a different configurable period of time) after that time, I'd like cell B1 to be automatically locked so that a value cannot be entered. The cell lock should be password protected so that it can be manually unlocked by a password holder as desired.

Any help would be appreciated!

Thank you,
Jacob
