I'm using this contrib's version posted by webmasterkai on Tue, 10/23/2007, with drupal 5.9 and ubercart 5.x-1.0.

Unfortunately I couldn't get the module to work, since I got the following error, when I try to put Order Minimum: € 0.00, Order Maximum: € 49.99, Shipping Rate: € 10.00, Shipping Percentage: % 0. For Euro values, it is ok to use the decimal separator "."; I am also getting errors in the Checkout Page:

user warning: Unknown column 'percent' in 'field list' query: INSERT INTO shop_uc_ratequotes (min, max, rate, percent) VALUES (0, 49.99, 10, 0) in /var/www/vhosts/mywebsite.com/subdomains/shop/httpdocs/includes/database.mysql.inc on line 172.

I had a previous version of this module installed and forgot running update.php. So the problem was solved running update.php. Module is now working fine.
