Hi Mohamed,
Attached is a screenshot of my PayPal settings...as you can see, "Send details of the order" option is set to YES.
You said that it's working fine for you...I do not understand this. Did you register/login at my site with a California address and try to make a purchase?
I have registered with my California address and the 9% tax does not appear when I check out.
If I take the next step and I go to buy the item in PayPal, the tax does not appear on the PayPal order summary.
If it's working for you, why is it not working for me?
You now have screen shots for all my settings...what am I missing?
How can I get it to work for me?
Mort
