Unlock cell, add data, re-lock cell.

All has to be by code. No auto-function for this. You must visit the
programming sub-group.

First...........select all cells on sheet and format them to unlocked.

Add this event code to the worksheet module.

Private Sub Worksheet_Change(ByVal Target As Excel.Range)
On Error GoTo enditall
Application.EnableEvents = False
If Target.Cells.Column = 3 Then
ActiveSheet.Unprotect Password:="justme"
n = Target.Row
If Me.Range("C" & n).Value < "" Then
Me.Range("C" & n).Locked = True
End If
End If
enditall:
ActiveSheet.Protect Password:="justme"
Application.EnableEvents = True
End Sub

When you enter a value in column C that cell will become locked for
editing.

In what manner other than the weakness of Excel's internal security
which is always the issue.

OP can lock the project from viewing so's users cannot see the
password.

How would the user edit an incorrect entry in the amount column?

Copy/paste this event code to Thisworkbook module.

Private Sub Workbook_BeforeClose(Cancel As Boolean)
Sheets("yoursheetname").Protect Password:="justme"
End Sub

NOTE: as others have pointed out, Excel's internal security is quite
weak and protection of cells and sheets will serve only to prevent
accidental overwriting of formulas or data.

A user determined to change data can easily crack the password
protection.

GS also asked "how will user correct a mistake in data entry if cells
are locked"?

What will you do if users do not enable VBA when they open the
workbook?

Have you considered these issues?

Hello Gord,

The cells I want to lock are already unlocked in a protected worksheet and the above code works perfect for column C. I have a need to do the same thing on columns A thru N. How is the above code modified to do this?

Many thanks,

Jim
