That sounds like the right approach.
I have created the registration pages using security assist and form builder. In the server behaviours there is a standard dreamweaver insert behaviour adding the form values to the user table, however this doesnt seem to allow static values to be assigned, only form elements.
If i use the data assist insert behaviour to assign the access level, this creates an entirely new table entry. Is there a way i can add a static value to the table using the insert behaviour created by form builder, along with the rest of the form data?
