Line 12: Public Sub AddCart(ByVal CustomerID As Integer, ByVal ProductID As Integer, ByVal Qty As Double)
Line 13: 'Add a single row item to the cart
Line 14: Dim objCmd As New OleDbCommand("uspAddCart", objConn)
Line 15: objCmd.CommandType = CommandType.StoredProcedure
The error refers to line 14. At one stage this was working. Now all of a sudden it's not! And all functions containing code like line 14 now fail the same way. Any ideas please?
