I am developing a website using Dreamweaver UltraDev4 on an NT network. I am trying to create a log in and registration page using an Access DB. The server i am uploading my pages to is a unix server, which uses chilisoft SW. In Dreamweaver, when I create server behaviours, I get an error message when I try to preview the site in a browser and it will not load. Also when I log into NT for a new session, The behaviours are not saved from the previous session and I have to start again. Can anyone offer any advice please?
