Addressing a Dynamic Named Range inside of Select Case

Question

I am building a page where Col H should be a drop down box which is dependent on Col A.

Col A is already set up to use Validation List using a Dynamic Named Range which is specified on a hidden sheet named Data.

Also, on the Data sheet, I have specified the 3 lists which are dependent on Col A and have already made them a Dynamic Named Range as well.

So far, in VB code, I have

1. Taken the first word, before a comma, from the selection made in Col A and used that as my "Group" identifier.

2. Capitalized all text inputted to Col B (not relevant).

Now, I need to specify what to make as possible selections in Col H. You can see in the case "Desktop" my attempt to do this, however, it does not work and gives me an "Object Required" error.

Old Code:

Private Sub Worksheet_Change(ByVal Target As Range)
    On Error GoTo Whoa

    Application.EnableEvents = False

    If Not Intersect(Target, Columns(1)) Is Nothing Then
        If Target.Value <> "" And InStr(1, Target.Value, ",") Then
            Select Case Split(Target.Value, ",")(0)
               Case "Desktop": Range("H" & Target.row).Value = 
                    Data.Range("List_Desktops").Address
               Case "Laptop":  Range("H" & Target.row).Value = "Laptop"
               Case "Server":  Range("H" & Target.row).Value = "Server"
               Case Else:      Range("H" & Target.row).Value = "N/A"
            End Select
        End If
    ElseIf Not Intersect(Target, Columns(2)) Is Nothing Then
        If Not Target.HasFormula Then Target.Value = UCase(Target.Value)
    End If

LetsContinue:
    Application.EnableEvents = True
    Exit Sub
Whoa:
    MsgBox Err.Description
    Resume LetsContinue
End Sub

New Code:

Private Sub Worksheet_Change(ByVal Target As Range)
    Dim i As Long, LastRow As Long, n As Long
    Dim MyCol As Collection
    Dim SearchString As String, TempList As String

    On Error GoTo Whoa

    Application.EnableEvents = False

     '~~> Find LastRow in List_Descriptions
    LastRow = Sheet2.Range("A" & Rows.Count).End(xlUp).row

    If Not Intersect(Target, Columns(1)) Is Nothing Then
        Set MyCol = New Collection

         '~~> Get the data from List_Descriptions into a collection
        For i = 1 To LastRow
            If Len(Trim(Sheet2.Range("A" & i).Value)) <> 0 Then
                On Error Resume Next
                MyCol.Add CStr(Sheet2.Range("A" & i).Value), CStr(Sheet2.Range("A" & i).Value)
