sorry here is my function

Function UpdateShoppingCart(ByVal cartid As String, ByVal productid As
Integer, ByVal Quantity As Integer)
' Create Instance of Connection and Command Object
Dim conn As SqlConnection = New
SqlConnection("server=localhost;uid=sa;pwd=;database=golf")

Dim myCommand As SqlCommand = New SqlCommand("UpdateCart", conn)

' Mark the Command as a SPROC
myCommand.CommandType = CommandType.StoredProcedure

' Add Parameters to SPROC
Dim parameterCartID As SqlParameter = New
SqlParameter("@CartID", SqlDbType.NVarChar, 50)
parameterCartID.Value = cartid
myCommand.Parameters.Add(parameterCartID)

Dim parameterProductID As SqlParameter = New
SqlParameter("@ProductID", SqlDbType.Int, 4)
parameterProductID.Value = productid
myCommand.Parameters.Add(parameterProductID)

Dim parameterQuantity As SqlParameter = New
SqlParameter("@Quantity", SqlDbType.Int, 4)
parameterQuantity.Value = parameterQuantity
myCommand.Parameters.Add(parameterQuantity)

' Open the connection and execute the Command
conn.Open()
myCommand.ExecuteNonQuery()
conn.Close()
End Function

and here is the code that calls the function

Dim ProductID = DGridBasket.DataKeys(e.Item.ItemIndex)

Dim Qty As String = CType(e.Item.FindControl("Quantity"),
TextBox).Text

Dim mycartDetails As golfstore.ShoppingCartDB = New
golfstore.ShoppingCartDB()
'get the current cartid
Dim cartID As String = mycartDetails.GetShoppingCartId()

mycartDetails.UpdateShoppingCart(cartID, ProductID, Qty)

Many Thanks
Paul

I think it means you have stated that a class implements an interface but
did not implement the required function

You are trying to use a function that operates on members of the
IConvertible interface, but an object you are trying to pass to that
function does not implement the IConvertible interface and therefore does
not have any of the required members, thus the error.
