how to update metadata on a line item in an order.

[dw5304]

I am attempting to update metadata in a line item of an order.

I was able to update the order status its self but seem to have having issues figguring out how i should update meta data. I can get it to change but havent been able to get it to post and actually update the order any help would be appreciated.

    Dim id As Integer = txt_orderid.Text
    Dim response = Await wco1.Order.Update(CInt(Math.Truncate(id)), New Order With {.status = "completed"})




        order = Await wco1.Order.Get(txt_orderid.Text)




        For Each lineitem In order.line_items
            lineitem.meta_data(3).display_value = "testing"

        Next
