Confused by sorted list of a sorted list

[J L]

I want to create a sorted list whose values are themselves sorted
lists. I wrote the following simple test program but it does not
behave as I would expect.

What I wanted to do was have the doorConflictList be keyed on a door
ID and contain a sorted list called conFlictList. I wrote this
expecting the following

doorConflictList should end up with 3 items.
Item 1 would be a sorted list with 1 item
Item 2 would be a sorted list with 2 items
Item 3 would be a sorted list with 3 items.

I expected to see :

Door 0
Value 0
Door 1
Value 0
Value 1
Door 2
Value 0
Value 1
Value 2

but instead I see:

Door 0
Value 0
Value 1
Value 2
Door 1
Value 0
Value 1
Value 2
Door 2
Value 0
Value 1
Value 2

What am I doing wrong?

Here is the code :

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
Dim conFlictList As New SortedList
Dim doorConflictList As New SortedList
Dim i As Integer
Dim m As Integer
Dim door As Integer
Dim numberOfDoors As Integer = 3
For door = 0 To numberOfDoors - 1
conFlictList.Clear()
For i = 0 To door
conFlictList.Add("Key " & i.ToString, "Value " &
i.ToString)
Next
doorConflictList.Add("Door " & door.ToString, conFlictList)
Next
Dim strMessage As String = ""
If doorConflictList.Count > 0 Then
For i = 0 To doorConflictList.Count - 1
strMessage += doorConflictList.GetKey(i) & vbCrLf
Dim theConflicts As SortedList = _
CType(doorConflictList.GetByIndex(i), SortedList)
If theConflicts.Count > 0 Then
For m = 0 To theConflicts.Count - 1
strMessage += " " & theConflicts.GetByIndex(m) &
vbCrLf
Next
End If
Next
End If
MessageBox.Show(strMessage)
End Sub

TIA

Opps...embarrasing...I see it now...scope issue...
Needed to move the
Dim conflictlist as New SortedList
into the loop creating it, else I was pointing to the same sorted
list every time and hence the last one filled had the 3 values...well
that was not well stated but I see the problem...
