Try event code. An example


'-----------------------------------------------------------------
Private Sub Worksheet_Change(ByVal Target As Range)
'-----------------------------------------------------------------
Const WS_RANGE As String = "H1:H10" '<=== change to suit

On Error GoTo ws_exit:
Application.EnableEvents = False
If Not Intersect(Target, Me.Range(WS_RANGE)) Is Nothing Then
With Target
Select Case .Value
Case 1: .Interior.ColorIndex = 3 'red
Case 2: .Interior.ColorIndex = 6 'yellow
Case 3: .Interior.ColorIndex = 5 'blue
Case 4: .Interior.ColorIndex = 10 'green
End Select
End With
End If

ws_exit:
Application.EnableEvents = True
End Sub

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.

Hi, I have values in a cell that changes if the cell next to it changes.
The values are five constant values, i.e. "Critical Criteria",
"Non-Critical
Criteria" etc.
I need to colour the cell a different colour based on each unique value.

The conditional formatting only caters for 3 conditions. How do I do this.
I
do not have knowledge of using macros.

Appreciate it.
