I have created some drop down lists and have unchecked the "Show error alert after invalid data is entered" under the Error Alert tab to enable manual entry into the cell. The problem that I am encountering is that I can enter data manually into the cell that also contains the drop down only if the sheet is unprotected. As soon as I protect the sheet, manual entry is no longer allowed. I have verified that the cells I want to allow manual entry in are unlocked. Am I missing something?
