paypal sandbox
Couple of questions,
1. I created the proper sandbox accounts, but not able to test.
2. Calculating shipping issues I can't seem to figure out how to properly set up the shipping. I want it to calculated when client enters their shipping address. So far it calculating but its not doing it correctly. I want it to calculate shipping for separate line items. Then when i click continue to be redirected to paypal it doesn't show the correct total with shipping included?
below is the testing site and i included files
