2. The Lite version does not support server-side Javascript customization. In the professional version, all forms can trigger our server-side Javascript scripting engine to execute complex business logic. Basically any business logic that you would like to execute, but cannot be covered by Ragic's existing functions, can be covered by server-side scripting.
3. You can only have one system administrator that can access the design and backend in the Lite version while the professional version has no limit.
