Setting Session Variable
I have created my cart with the tax rule specifically for the state in which our business is located, where if ship to address is located within our state, then state sales tax is charged. This tax rule functions perfectly.
We also have nexus in three other states based on our delivery routes. Can I add the tax rules for these states in eCart1_PHP.php based on if and else if statements? Has the session variable in confirm.php (discussed above) already been created due to my original state tax rule? Sorry, I think I am just needing a little more clarity as to variable tax rules... thank you
