I apologize, I had thought you were using eCart. If you go into your Download center, go to your PayPal eCommerce Toolkit downloads and under Extensions there is a PayPal eCommerce Toolkit Recipes download. This has tutorials in it that will be helpful for you in setting up for taxing and shipping. One you've installed this, you can go to Help->WebAssist->WA PayPal Recipes in Dreamweaver to access the help documents. Sorry again for the confusion.
