Kode til Bankoplader (med kontrol for dubletter)

Jeg skal have lavet en masse bankplader via en Excel database med 27 rækker for hver plade. Jeg har i et forum på nettet fundet en VBA kode jeg tror virker, men jeg er lidt bekymret for at den kontrollerer for dubletter. Er der klog mand/kvinde i dette forum, der kan hjælpe med svar? Koden er nedenfor.

Option Base 1
Option Explicit

Sub main()
Dim lAntal As Long, s As Long
lAntal = Application.InputBox("Hvor mange plader ?")
For s = 2 To lAntal + 1
   
    Range("D" & s & ":AD" & s) = Make27Numbers

Next
End Sub


Function Make27Numbers()
Dim TmpArray(27)
Dim k As Long, z As Long, i As Long, j As Long, x As Long, y As Long
k = 0
z = 0
For i = 0 To 80 Step 10
    j = 0
    While j < 3
        If i = 0 Then y = 1 Else y = 0
        If i = 80 Then z = 1 Else z = 0
        x = rndbetween(i + y, i + 9 + z)
        If Not IsInArray(TmpArray, x) Then
            k = k + 1
            TmpArray(k) = x
            j = j + 1
        End If
    Wend
Next
BubbleSort TmpArray()
PickOut15 TmpArray
Make27Numbers = TmpArray
End Function


Function IsInArray(MyArray, TestValue)
IsInArray = IIf(UBound(Filter(MyArray, TestValue)) < 0, False, True)
End Function


Function rndbetween(low, high)
Dim tmp As Long
tmp = high - low + 1
rndbetween = Int(Rnd() * tmp) + low
End Function


Sub PickOut15(list())
Dim skema(3, 9)
Dim i As Long, j As Long, lRow As Long, lCol As Long, x As Long
Dim tal5 As Long, tal3 As Long
Randomize Timer
For i = 1 To 3
    For j = 1 To 9
        skema(i, j) = 1
    Next
Next
Do Until x = 12
    lRow = Int(Rnd() * 3) + 1
    lCol = Int(Rnd() * 9) + 1

    If skema(lRow, lCol) = 0 Then GoTo hop
    skema(lRow, lCol) = 0
    tal5 = 0
    tal3 = 0
    For i = 1 To 9
        tal5 = tal5 + skema(lRow, i)
    Next
    For i = 1 To 3
        tal3 = tal3 + skema(i, lCol)
    Next
    If (tal5 >= 5 And tal3 >= 1) Then x = x + 1 Else skema(lRow, lCol) = 1
hop:
Loop
x = 0
For i = 1 To 9
    For j = 1 To 3
        x = x + 1
        If skema(j, i) = 0 Then list(x) = "TOM"
    Next
Next
End Sub


Sub BubbleSort(list())
    Dim First As Integer, Last As Long
    Dim i As Long, j As Long
    Dim Temp As Long
   
    First = LBound(list)
    Last = UBound(list)
    For i = First To Last - 1
        For j = i + 1 To Last
            If list(i) > list(j) Then
                Temp = list(j)
                list(j) = list(i)
                list(i) = Temp
            End If
        Next j
    Next i
End Sub
