Hi,
AFAIK as long as you inherit the calctaxinterface and implement...
getCartTotals(ByVal PortalID As Integer, ByVal CartID As String, ByVal objCartTotals As CartTotals, ByVal CountryCode As String, ByVal TaxNumber As String)
in your class it should work. I see from your provider name above your using the "getCartTotals" as the type name in your dll, is this correct?...you should be calling it by the class name, not the function call name!
