Here is the definiton of a function:

Private Function GetData(ByVal tcQuery As String, ByVal tnProcess As Integer) As String
End Function

Then, as soon as I added the second parameter, all those lines have been representated as an error as they only pass one parameter:

<WebMethod()> _
Public Function NetGetWishListRatingLast100() As String
   Return Me.GetData("31")
End Function
