Folks,
I'd like to check to see if a year has already been entered?

In the AddYear macro, after the Yearly value is entered add

    Dim sht As Worksheet
    For Each sht In Worksheets
        If InStr(1, sht.Name, Right$(Yearly, 2)) > 0 Then
            MsgBox "Tabs for the year " & Yearly & " already exist in the workbook. Please delete them and/or try again"
            Exit Sub
        End If
    Next

In other words the following.

Lines 7 and 16 to 21 are new.

Sub AddYear()

  ' add year
    Dim Yearly As String
    Dim lngIndex As Long
    Dim strYr As String
    Dim sht As Worksheet
    
    Yearly = InputBox("Please enter a 4 digit year to append to the added rows")
'    If Yearly < "2014" Or Yearly > "2050" Then
    If Yearly < Year(Now) Or Yearly > Year(Now) + 2 Then
        MsgBox "Invalid Year please try again"
        Exit Sub
    End If
    
    For Each sht In Worksheets
        If InStr(1, sht.Name, Right$(Yearly, 2)) > 0 Then
            MsgBox "Tabs for the year " & Yearly & " already exist in the workbook. Please delete them and/or try again"
            Exit Sub
        End If
    Next
    
    Range("B6:B17").Select
    Selection.NumberFormat = "General"
    Selection.Value = Yearly
    strYr = " " & Right$(Yearly, 2)
    gstrYear = Right$(Yearly, 2)
    'Append worksheet

    For lngIndex = 1 To 12
        ' MonthName(lngIndex, True) returns "Jan" when lngIndex is 1
