Loop to create Object excel vba - excel

Question

I tried to get the unique value of each column in the range "RD" and display them in single column. I need to create an object ("scripting.Dictionary") where there are just as many as the number of columns in Range "RD". I tried this code but it resulted in "Run time error 13".
Private Sub CommandButton1_Click()
Range(Me.RefEdit1).Name = "RD"
Range(Me.RefEdit2).Name = "OT"
Dim d As Object, c As Variant, i As Long, s As Long
Dim JK As Long
Dim o As Collection
JK = Range("RD").Columns.Count
Set d = CreateObject("Scripting.Dictionary")
For k = 0 To JK + 1
d.Item(k) = CreateObject("Scripting.Dictionary").Item(k)
c = Range("RD").Columns(k + 1)
If d.Exists(k) Then
d.Item(k) = d.Item(k) + 1 'increment
Else
d.Item(k) = 1 'set as 1st occurence
End If
For i = 1 To UBound(c, 1)
d.Item(k)(c(i, 1)) = 1
Next i
Range("OT").Cells((k * 5) + 2, 2).Resize(d.Item(k).Count) = Application.Transpose(d.Item(k).Keys)
Range("OT").Cells((k * 5) + 2, 2).Resize(d.Item(k).Count).Sort Key1:=Range("OT").Cells((k * 5) + 2, 2).Resize(d.Item(k).Count)
Next k
End Sub

I'm adding some code below to help loop through a list, looking for unique values, and adding them to a new column. In my example, I enclose the entire functionality into a single loop for efficiency. I'm also adding the unique values to a new column in Sheet2 starting with cell A1.
Let me know if you need any additional help.
EDITED CODE BASED ON A MISUNDERSTANDING:
Private Sub CommandButton1_Click()
Dim oDict As Object
Dim rngToScrub As Range
Dim rngNewColumnToStoreUnique As Range
Dim oCol As Range
Dim cel As Range
Set rngToScrub = Range(Me.RefEdit1.Value)
Set rngNewColumnToStoreUnique = Sheet2.Range("A1")
For Each oCol In rngToScrub.Columns
Set oDict = CreateObject("Scripting.Dictionary")
For Each cel In oCol.Cells
If oDict.exists(cel.Value) Then
'Do Nothing for Now
Else
oDict.Add cel.Value, 0
rngNewColumnToStoreUnique.Value = cel.Value
Set rngNewColumnToStoreUnique = rngNewColumnToStoreUnique.Offset(1)
End If
Next cel
Set oDict = Nothing
Next oCol
End Sub
Old code: Misunderstood requirements
Private Sub CommandButton1_Click()
Dim oDict As Object
Dim rngToScrub As Range
Dim rngNewColumnToStoreUnique As Range
Dim cel As Range
Set oDict = CreateObject("Scripting.Dictionary")
Set rngToScrub = Range(Me.RefEdit1.Value)
Set rngNewColumnToStoreUnique = Sheet2.Range("A1")
For Each cel In rngToScrub
If oDict.exists(cel.Value) Then
'Do Nothing for Now
Else
oDict.Add cel.Value, 0
rngNewColumnToStoreUnique.Value = cel.Value
Set rngNewColumnToStoreUnique = rngNewColumnToStoreUnique.Offset(1)
End If
Next cel
End Sub
