In lines 46-48, you set the type of database that you're going to use (default is "access"). Choose the appropriate one by deleting the apostrophe (comment) in front of the line.
Then in lines 50-61, you have to set the path and method of connecting to your database. Again, if you're using Microsoft Access, you would want to use one of the choices in lines 54-56. Line 56 is the simplest method - simply delete the apostrophe and then change the path from "c:\inetpub\dbroot\snitz_forums_2000.mdb" to wherever you have it stored.<
