here is the deal

i have 10 products

and 5 shipping options

the first one is:

regular postage - 1 bottle $11 each additional bottle $6

5 - 7 day express 1 bottle $30 each additional bottle $6

and so on.

can someone assist me in coming up with a javascript that will tally the shipping, then post that total to paypal.

i want to be able to post those values into the browser in case the user wants to shop some more.

can someone do this?

contact me if you have an idea
