Gilles, thanks for all your 'contributions'. We appreciate what you've done.

I must chose to create a TAX PROVIDER or find another simple shopping solution. I say 'simple' because we have numerous SmithCarts installed and those are a real pain to setup for clients. This store is simple and elegant for that alone.

In the US, the seller charges tax based on the buyer location. If the buyer is in ANY OTHER state than the seller, then no tax is charged.

This makes the condition fairly logical; compare the buyer state to the seller state and IF match, then TAX.

Any tips on how to add this condition to the tax provider?

Hi Gilles,

 I'm trying to add a new AddressProvider and running into an issue.  I basically copied the Default and renamed the project / namespaces.  I can get it to load a a provider in the Store Admin drop down.  I can select it, and set it as the Provider to use.  However, when the Checkout control loads the Address step, it throws an error here;

addressCheckoutControl = (AddressCheckoutControlBase)addressProvider.GetCheckoutControl(this, ModulePath);

The AddressCheckoutControlBase used in the Checkout control is a direct reference to the Default provider, so when the NewAddressProvider tries to load the checkout control, the cast fails with this exception;

 The base class includes the field 'addressBilling', but its type (DotNetNuke.Modules.Store.Providers.Address.NewAddressProvider.StoreAddress) is not compatible with the type of control (ASP.desktopmodules_store_providers_addressproviders_defaultaddressprovider_storeaddress_ascx).

 Should the AddressCheckoutControlBase be part of the DotNetNuke.Store.Providers project?  I don't want to change anything but what's in my new Address Provider, but not sure what to do here?

Any ideas? - or is there a walk through for how to add a new Address Provider?

 Thanks for your help,

Jay
