Enhancement to Macro for Driving Dynamic Time Horizon

I have a great macro/WS that DMille wrote for me that provides for a Dynamic Time Horizon. The attached model has the ability to add new "Use Cases" and when it does, the Time Horizon capability does not work correctly.  When the rows are replicated (i.e. click the + User Case button), and then you change the Time Horizons, the new User Cases do not respond accordingly.  The original one does but not the new ones.  I think it is because it is "hard coded" into the macro.  I think it's in these two reference points:

Set rngClear = Range("AJ2", Cells(4, Columns.Count)).Resize(6)
       
        rngClear.ClearContents
       
        numPeriods = Range("AB3")

Thank you in advance.....

I think I've sorted the problem, as the calculations need to be based on the Target row, while also keeping the timespan in row 2 expanded to the max needed based on any entry in AB.

Please try this code and advise:
'New code to expand months
Private Sub CheckExpMonths(ByVal Target As Range)
Dim numPeriods As Long
Dim periodDisplay As Long
Dim rngClear As Range
Dim LastCol As Long

    
    If Not Intersect(Target, Range("AB:AB")) Is Nothing Then
        Application.EnableEvents = False
        
        LastCol = Cells(4, Columns.Count).End(xlToLeft).Column
        
        Set rngClear = Range("AJ" & Target.Row - IIf(Target.Row = 3, 1, 0), Cells(Target.Row, Columns.Count)).Resize(6)
        
        rngClear.ClearContents
        
        numPeriods = Range("AB" & Target.Row)
        
        periodDisplay = Evaluate("=MAX(AB:AB)") 'get max periods to display
        If numPeriods > 1 Then
            With Range("AI2")
                .Resize(, periodDisplay).DataSeries Rowcol:=xlRows, Type:=xlChronological, Date:=xlMonth, Step:=1, Trend:=False
            End With
        End If
    
        Range("AI" & Target.Row & ":AI" & Target.Row + 1).Copy Range("AI" & Target.Row & ":AI" & Target.Row + 1).Resize(, numPeriods)
        
        Application.EnableEvents = True
    End If
            
End Sub

This post is more clever and uses the latest post from the prior question which for some reason you weren't.
'New code to expand months
Private Sub CheckExpMonths(ByVal Target As Range)
Dim numPeriods As Long
Dim periodDisplay As Long
Dim rngClear As Range
Dim LastCol As Long

    
    If Not Intersect(Target, Range("AB:AB")) Is Nothing Then
        Application.EnableEvents = False
        
        LastCol = Cells(4, Columns.Count).End(xlToLeft).Column
        
        Range("AJ2", Cells(2, Columns.Count)).ClearContents
        
        Set rngClear = Range("AJ" & Target.Row - IIf(Target.Row = 3, 1, 0), Cells(Target.Row, Columns.Count)).Resize(3)
        
        rngClear.ClearContents
        
        numPeriods = Range("AB" & Target.Row).Value
        
        periodDisplay = Evaluate("=MAX(AB:AB)") 'get max periods to display
        If numPeriods >= 1 Then
            With Range("AI2")
                .Resize(, periodDisplay).DataSeries Rowcol:=xlRows, Type:=xlChronological, Date:=xlMonth, Step:=1, Trend:=False
            End With
            Range("AI" & Target.Row & ":AI" & Target.Row + 1).Copy Range("AI" & Target.Row & ":AI" & Target.Row + 1).Resize(, numPeriods)
        End If
        
        Application.EnableEvents = True
    End If
            
End Sub

Bright - you need to use the latest post, above.  After more testing more tweaks were necessary.
