I was unsure which form page you might have been looking for. The general approach I use is to first look to see if the site uses a GET or a POST. If it is a GET (which it appears to be), then I simply fill in a sample search, grab the resulting URL and fit it into a template of the following form: ************** REBOL [] site: author: "" title: "" submit: "Begin+Search" new_used: "*" binding: "*" isbn: "0-393-96945-2" keywords: "" min_price: "" max_price: "" currency: "USD" mode: "advanced" st: "sr" ac: "qr" either error? try [ page-return: read rejoin [ site {?author=} author {&title=} title {&submit=} submit {&new_used=} new_used {&binding=} binding {&isbn=} isbn {&keywords=} keywords {&min_price=} min_price {&max_price=} max_price {&currency=} currency {&mode=} mode {&st=} st {&ac=} ac ] ][ page-return: "error" ][ print page-return ] ******************* I usually embed this functionality into a function and pass in only the field that will be queried. Then where I have "print page-return", I usually put my parse functionality and return either the parsed info or an appropriate error message. Hopefully this will get you started. POST is a little different. I've done a few of those and can probably find an example if needed. Good luck. --Scott Jones
