I have everything all setup. The site is running FEC COWA (NUMINIX), and 1.3.9.

FEC simply combines the checkout modules into a one page format. I can checkout with both FEC enabled and not.

FEC enabled no tax shows at all... Now since the TaxCloud hasn't a proper order total module in the admin I am unsure of how it calls and from where to add it.

With regular Zen Cart checkout I get tax no problem and upon confirming order I get...


Array ( [0] => A matching lookup could not be found for this authorization )


Any ideas? For Washington this is really necessary.
