"Cannot change" to me means "locked"

Locked means sheet protection must be applied.

When you save at end of day you can run event code to look down column A and
find today's date or earlier.

Then lock the cells in column C

Does that work for you?

First select all cells on Sheet1 and clear the "locked" property.

Then paste this code into Thisworkbook module.

Private Sub Workbook_BeforeClose(Cancel As Boolean)
Dim c As Range
Dim rng1 As Range
Dim ws As Worksheet
Set ws = ThisWorkbook.Sheets("Sheet1")
Set rng1 = ws.Range(Cells(1), Cells(Rows.Count, 1).End(xlUp))
ws.Unprotect Password:="justme"
For Each c In rng1
If c.Value = Date Or c.Value < Date Then
c.Offset(0, 2).Locked = True
Else: c.Offset(0, 2).Locked = False
End If
Next
ws.Protect Password:="justme"
ThisWorkbook.Save 'save no ask
End Sub

Gord,

Picture a check register. Basically, the idea is to enter today's
date in column A. My computerized register balances my daily entries
and returns a balance for each transaction in column C. When I close
the file at the end of the day, I want the amount reflected in C to
become permanent so that it cannot be changed at a later date.
Therefore, any entry that reflects today's date in A will become
permanent (fixed) in C. Sorry about the confusion. I hope this
helps.
