for each c in range(“a4:a10”)
  if c.value=c.offset(,1).value then c.offset(,1).locked=true

Dear Paul, 
First let me thanks you for prompt reply.

Private Sub Worksheet_SelectionChange(ByVal Target As Excel.Range) If 
Range("a4:a10").Value = "" Then Range("b4:B10").Locked = False Else 
Range("b4:b10").Locked = True End If End Sub

  Your request is somewhat confusing.

  "locking" a cell does not necessarily mean "grayed out".
  In order to lock a cell, two things have to happen.
  1) the "locked" property of the cell must be set.
  2) the sheet has to be protected (with or without a password)

  For the cell to be "Grayed Out" means that the font is a light gray.
  These two events are independent.

  Now, it IS possible to create an event that checks for a change in Column C.
  If the cell has a value, a)uprotect the sheet, b) change the "locked" 
property  to "true" on the cell in the same row as the changed cell, and column 
"D", c) change the font color to Gray.

  You didn't mention it, but were you looking for a VBA solution?
  what version of excel are you using?
  what do you know about VBA programming?
  what have you tried?

  Now, about the "vice versa":
  The term means "the other way around".
  So, do you mean that if a cell in column D has a value, then the 
corresponding cell in column C gets locked?
  or do you simply mean that if C is blank, the D is UNLOCKed?

  Hay looking for help ..



       Column       C
         D
        
          open for entry
        
       a
         Locked
        
       d
         Locked
        
       a
         Locked
        
          open for entry
        

  If any value is in Column C Cells then Column D Cell   (In same row) get 
locked (Grayed out) and vice versa.
