I have a list box with a numerous items. I want to put a spinbutton beside it so that the user can select and item to move up and down in the list. As they move it I want to adjust the data on the excel sheet accordingly. I know how to move the data. but i don't know how to link the spinbutton and control how to move the data as it is pressed up or down. Thanks

Try using the following code.  Change SpinButton1 to the name of the name of your spin button control and change ListBox1 to the name of your list box control.
Private Sub SpinButton1_SpinDown()

Call MoveListItem(True)

End Sub
 

Private Sub SpinButton1_SpinUp()

Call MoveListItem(False)

End Sub
 

Function MoveListItem(blnShiftDown As Boolean)
 

If ListBox1.ListIndex < 0 Or _

ListBox1.ListIndex = 0 And Not blnShiftDown Or _

ListBox1.ListIndex = ListBox1.ListCount - 1 And blnShiftDown Then Exit Function
 

Dim i As Integer

Dim strListItems() As String

ReDim strListItems(ListBox1.ListCount - 1)
 

For i = 0 To ListBox1.ListIndex - IIf(blnShiftDown, 1, 2)

    strListItems(i) = ListBox1.List(i)

Next i

strListItems(i) = ListBox1.List(ListBox1.ListIndex + IIf(blnShiftDown, 1, 0))

strListItems(i + 1) = ListBox1.List(ListBox1.ListIndex - IIf(blnShiftDown, 0, 1))
 

For i = ListBox1.ListIndex + IIf(blnShiftDown, 2, 1) To ListBox1.ListCount - 1

    strListItems(i) = ListBox1.List(i)

Next i
 

ListBox1.List = strListItems
 

End Function

You can swap List items using just a temp string. No intermediate array needed.
Following code moves List items Up or Down, checks for upper;lower bounds, and updates the ListIndex.

Option Explicit
 

Private Sub Form_Load()

   Dim i As Long

   For i = 1 To 10

      ListBox1.AddItem "Item " & Chr(64 + i)

   Next

End Sub
 

Private Sub SpinButton1_SpinDown()

   Dim SelIndex         As Long

   Dim Temp             As String

   

   SelIndex = ListBox1.ListIndex

   If (SelIndex >= 0) And (SelIndex < ListBox1.ListCount - 1) Then

      Temp = ListBox1.List(SelIndex + 1)

      ListBox1.List(SelIndex + 1) = ListBox1.List(SelIndex)

      ListBox1.List(SelIndex) = Temp

      ListBox1.ListIndex = ListBox1.ListIndex + 1

   End If

End Sub
 

Private Sub SpinButton1_SpinUp()

   Dim SelIndex         As Long

   Dim Temp             As String

   

   SelIndex = ListBox1.ListIndex

   If SelIndex > 0 Then

      Temp = ListBox1.List(SelIndex - 1)

      ListBox1.List(SelIndex - 1) = ListBox1.List(SelIndex)

      ListBox1.List(SelIndex) = Temp

      ListBox1.ListIndex = ListBox1.ListIndex - 1

   End If

End Sub
