using the paypal buttons provided, when i go to the buy it now button properties with shipping can someone please explain what the difference is between "Base shipping", "Extra Shipping" and "Handling Costs" plus if someone was to buy someone from the UK (as i live in the UK) the shipping would be about £5 but how do i change this for if someone from america was to purchase the item :S


Also the other problem i am trying to get my head around is on the product page for a t-shirt how do i make a drop down list which will let them choose the size and colour of shirt they want....i can't work it out :(

please help. cheers
