  Can anyone help me

  You can only generate driving directions from one point to another on any given map (no multi-point routing). You can have multiple map controls on a single page, however, and so I think you should be able to generate a different set of driving directions on each map, but I haven't tried that yet.

  What kind of errors are you seeing

  Here is the code I am using to render the maps, and the error I am getting is...

  Code:

  Protected Sub Page_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.PreRender

  Dim js As String = ""

  Dim ds As DataSet

  Dim CurrentID As Integer = 0

  Dim i As Integer = 0

  If Not ViewState("Agenda") Is Nothing Then

  ds = ViewState("Agenda")

  Else

  Exit Sub

  End If

  For CurrentID = 0 To ViewState("Totals") - 1

  js = ""
