Conditional data entry
I am using excel 2003.
How can I 'grey out' or prevent data entry in a cell based on what is selected from a dropdown box in another cell?
Anwsers to the Problem Conditional data entry
You could use an event.
For example, to prevent B4 from being used based on A4's value (all cells should be unlocked and the sheet protected):
Private Sub Worksheet_Change(ByVal Target As Range)
If Target.Address = "$A$4" Then
Application.EnableEvents = False
If Target.Value = "Specific Value" Then
Range("B4").Locked = True
Range("B4").Locked = False
Application.EnableEvents = True
Or, use Data Validation on cell B4, using the custom formula
- Open Internet Explorer.
- Go to "Tools > Internet Options > Advanced Tab".
- Uncheck "Enable third-party browser extensions".
- Click "Apply".
- Reboot your computer.
