Randomise numbers without repeating the number - vba

Question

My end result is to output the names in column A to column B in random order.
I have been researching but cant seem to find what I need.
So far I can kinda of randomise the numbers but its still giving me repeated numbers + the heading (A1).
I need it to skip A1 because this is the heading\title of the column and start at A2.
I assume once that is working correctly I add the randomNumber to a random name to Worksheets("Master Sheet").Cells(randomNumber, "B").Value ...something like that...?
OR if there is a better way of doing this let me know.
Sub Meow()
Dim CountedRows As Integer
Dim x As Integer
Dim i As Integer
Dim PreviousCell As Integer
Dim randomNumber As Integer
i = 1
PreviousCell = 0
CountedRows = Worksheets("Master Sheet").Range("A" & Rows.Count).End(xlUp).Row
If CountedRows < 2 Then
' If its only the heading then quit and display a messagebox
No_People_Error = MsgBox("No People entered or found, in column 'A' of Sheetname 'Master Sheet'", vbInformation, "Pavle Says No!")
Exit Sub
End If
Do Until i = CountedRows
randomNumber = Int((Rnd * (CountedRows - 1)) + 1) + 1
If Not PreviousCell = randomNumber Then
Debug.Print randomNumber
i = i + 1
End If
PreviousCell = randomNumber
Loop
Debug.Print "EOF"
End Sub

Here's a quick hack...
Sub Meow()
'On Error GoTo err_error
Dim CountedRows As Integer
Dim x As Integer
Dim i As Integer
Dim PreviousCell As Integer
Dim randomNumber As Integer
Dim nums() As Integer
PreviousCell = 0
CountedRows = Worksheets("Master Sheet").Range("A" & Rows.Count).End(xlUp).Row
ReDim nums(CountedRows - 1)
If CountedRows < 2 Then
' If its only the heading then quit and display a messagebox
No_People_Error = MsgBox("No People entered or found, in column 'A' of Sheetname 'Master Sheet'", vbInformation, "Pavle Says No!")
Exit Sub
End If
For i = 1 To CountedRows
rand:
randomNumber = randomNumbers(1, CountedRows, nums)
nums(i - 1) = randomNumber
Worksheets("Master Sheet").Range("B" & randomNumber) = Range("A" & i)
Next i
Exit Sub
err_error:
Debug.Print Err.Description
End Sub
Public Function randomNumbers(lb As Integer, ub As Integer, used As Variant) As Integer
Dim r As Integer
r = Int((ub - lb + 1) * Rnd + 1)
For Each j In used
If j = r Then
r = randomNumbers(lb, ub, used)
Else
randomNumbers = r
End If
Next
End Function

Answer 2

I've managed something similar previously using two collections.
Fill one collection with the original data and leave the other collection empty. Then keep randomly picking an index in the first collection, adding the value at that index to the second collection and delete the value from the original collection. Set that to loop until the first collection is empty and the second collection will be full of a randomly sorted set of unique values from your starting list.
***Edit: I've thought about it again and you don't really need the second collection. You can pop a random value from the first collection and write it directly to the worksheet, incrementing the row each time:
Sub Meow()
Dim lst As New Collection
Dim rndLst As New Collection
Dim startRow As Integer
Dim endRow As Integer
Dim No_People_Error As Integer
startRow = 2
endRow = Worksheets("Master Sheet").Cells(startRow, 1).End(xlDown).Row
If Cells(startRow, 1).Value = "" Then
' If its only the heading then quit and display a messagebox
No_People_Error = MsgBox("No People entered or found, in column 'A' of Sheetname 'Master Sheet'", vbInformation, "Pavle Says No!")
Exit Sub
End If
' Fill a collection with the original list
Dim i As Integer
For i = startRow To endRow
lst.Add Cells(i, 1).Value
Next i
' Create a randomized list collection
' Use i as a row counter
Dim rowCounter As Integer
rowCounter = startRow
Dim index As Integer
Do While lst.Count > 0
'Find a random index in the original collection
index = Int((lst.Count - 1 + 1) * Rnd + 1)
'Place the value in the worksheet
Cells(rowCounter, 2).Value = lst(index)
'Remove the value from the list
lst.Remove (index)
'Increment row counter
rowCounter = rowCounter + 1
Loop
End Sub
P.S. I hope there's an excellent story behind naming your sub Meow() :P
