This is a proiblem connecting to the database which could be coming from several things.
1. Check your user on MySQL, you should have a user created for the database you want to connect under the user administration.
2. Check your MyODBC connection, there is a test button on it, that should give you an idea of where the problem is.
3. Check your username and password on your connection settings on your ASP page.
The best is often to remove the user in the DB, remove the connection and start all over.
Hope this helps,
