I have a problem in excel Vba when I try to run this code, I have an error of subscript out of range:

```
Private Sub UserForm_Initialize()
  n_users = Worksheets(Aux).Range("C1").Value

  Debug.Print Worksheets(Aux).Range("B1:B" & n_users).Value

  ListBox1.RowSource = Worksheets(Aux).Range("B1:B" & n_users).Value

  ComboBox1.RowSource = Worksheets(Aux).Range("B1:B" & n_users).Value
  ComboBox2.RowSource = Worksheets(Aux).Range("B1:B" & n_users).Value

End Sub

```

And Debug.Print works well, so the only problem is in Range("B1:B" & n\_users).Value.
