I have a sheet with several hundred rows. Starting in Row 4 through the end of the sheet are mixed dates in column 1 and ALL rows from Row 4 through the end of the sheet hidden. I want to be able to type in a date in Cell A1 and have all rows that have that date in Column 1, Row 4 through the end of the sheet to become unhidden. Secondly, I would like to type some other code like "999" or something in Cell A1 to have ALL rows become unhidden. Thirdly, I would like to either type another code or just delete anything in Cell A1 and have ALL rows from Row 4 through the end of the sheet to become hidden again.
