flat rate shipping charges by state
I'm using eCart v6.1.3. I need to apply a flat shipping charge by state but I don't know where to start. I searched through the forum without any luck. I found a reference to "$_SESSION['eCartCheckoutForm_shipping_state_province']" but searching through all my pages did not return any results for that value. I am also concerned what happens if the visitor changes their address for shipping in PayPal after they complete the checkout form on the website.
