Excel - Dynamically changing list boxes

Experts:

I have attached a sample Excel workbook.  I want to be able to work with 5 drop down lists.  All of the lists are the same.  There are 5 items in each of the dropdowns, and at any given time, each dropdown list item displayed will NOT be duplicated in any of the other 4 dropdowns.  I want to be able to select any of 5 items in a specific dropdown list, and have the items "swap".

I know above is not a very good explanation.  Hopefully the sample attached will show what I need better than this explanation.

Thanks in advance.

Try this macro
Right-click on the sheet tab name
Select View code
Paste this code in the VBA window
Close the VBA window
Private Sub Worksheet_Change(ByVal Target As Range)
    Dim cel As Range
    Dim scel As Range
    Dim dv
    Dim dvn() As String
    Dim nf As Boolean
    If Target.Count = 1 And Not Intersect(Target, Range("G1:K1")) Is Nothing Then
        For Each cel In Range("G1:K1")
            If cel.Address <> Target.Address Then
                If cel = Target Then
                    dvn = Split(Replace(ThisWorkbook.Names(Replace(cel.Validation.Formula1, "=", "")).RefersTo, "=", ""), "!")
                    For Each dv In Sheets(dvn(0)).Range(dvn(1))
                        nf = False
                        For Each scel In Range("G1:K1")
                            If scel = dv Then nf = True: Exit For
                        Next scel
                        If Not nf Then cel = dv: Exit Sub
                    Next dv
                End If
            End If
        Next cel
    End If
End Sub

Just a very quick post to thank you for the above....  At present, I have not had an opportunity to try.  It will be very late this evening before I can test.

I just did not want you to think I am ignoring your post.

Thanks again,
Rick Norris

EXCELLENT, EXCELLENT solution.  It met every requirement!

After I looked at what I really need to happen, I now need additional help....  I've posted a follow up question.  I do hope that you can "modify" the code to accommodate my additional requirement that was not part of this original question.  I have provided a link to the new question.
