Conditional locking of a cell
Does someone know a way to prevent a user from entering data into a cell
unless there is something first entered into different cell. Here is an example of what I am trying to do. =IF(A1="",disable data entry in D1,enable data entry in D1) =IF(A1="",D1="") The application is a time sheet. I want to prevent a person from entering their hours until a billing code is first entered. In addition, if the billing code is deleted then I want to delete the hours booked against it as well. Thanks for any tips Best regards GordL |

right click on sheet tab, view code, paste this in:
Private Sub Worksheet_Change(ByVal Target As Range) If Intersect(Target, Range("A1")) Is Nothing And _ Intersect(Target, Range("D1")) Is Nothing Then Exit Sub If Range("A1").Value = "" Then Application.EnableEvents = False Range("D1").Value = "" 'Include a message, if desired MsgBox "A1 must have a value", vbOKOnly Application.EnableEvents = True End If End Sub 'Note that users can still input data into D1, but it is immediately deleted. 'While it might be possible to prevent this via some formula in data validation 'you needed to use VB anyway to clear D1, so I combined the two features -- Best Regards, Luke M *Remember to click "yes" if this post helped you!* "GordL" wrote: Does someone know a way to prevent a user from entering data into a cell unless there is something first entered into different cell.

I would be inclined to use a custom data validation for that. In Cell D1 select
Data -Validation - Custom | =A1 < "" and uncheck Ignore Blanks. Change the error message to something that indactes they need to enter a code Choose Ok. -- HTH...
