Sardines---------- 2

I forgot to add 2 pack of milk, Then I want to become like this

Milk--------------- 1
Sardines---------- 2
Milk--------------- 2..
But in My code this is What happen

Milk--------------- 3
Sardines---------- 2
Its Updated the QTy Instead Make A another Row.
HElo Guys,, This is My code..

Dim qtyadd As String
Dim subtotaladd As String
Dim itm As MSComctlLib.ListItem
Dim i As Integer


    Set itm = ListView1.FindItem(txtCode.Text)
     If Not itm Is Nothing Then
        itm.EnsureVisible
        itm.Selected = True
        
   qtyadd = Val(txtqty.Text) + Val(ListView1.SelectedItem.SubItems(2))
   subtotaladd = Val(lbltotal.Text) + Val(ListView1.SelectedItem.SubItems(4))
    ListView1.SelectedItem.SubItems(2) = qtyadd
    ListView1.SelectedItem.SubItems(4) = Format(subtotaladd, "###################.00")
Else
ListView1.ListItems.Add , , txtCode.Text
ListView1.ListItems.Item(ListView1.ListItems.Count).ListSubItems.Add , , txtproductname.Text
ListView1.ListItems.Item(ListView1.ListItems.Count).ListSubItems.Add , , txtqty.Text
