Navnet er omdefineret

Jeg får følgende fejlmeddelelse:

Navnet er omdefineret
/Ancillariacom_Local/site.asp, line 11, column 4
Dim g_sitename, g_bodytag

Min kode ser således ud:

<%
  'Globally define certain site metrics, such as it's name and domain...
  const g_sitename = "Ancillaria Tools"
  const g_domainname = "ancillaria.com"
 
  'g_bodytag is used to set elements of the style sheet that don't
  'work 100% in all browsers.
  const g_bodytag = "bgcolor=#FFFFFF leftmargin=0 topmargin=0 marginleft=0 margintop=0"

  Dim m_visit
  Dim g_sitename, g_bodytag
 
  Function Visit
      If IsEmpty(m_visit) Then
        Set m_visit = Server.CreateObject("WroxCommerce.Visit")
       
        m_visit.Configure g_sitename, g_domainname, "driver=SQL Server;" & _
                          "DATABASE=Ancillaria; UID=sa;PWD=pb16950;" & _
                          "Server=Ancillaria"
      End If
     
      Set Visit = m_visit
  End Function                       
%>

Hvad er der galt?
