Re: Strange Bizzare Problem

Is it possible that your database is ot updating immediately but on a delayed basis..some databases can be set to update on a delayed or immediate basis. If the update varaiables are derived from the database then these will not be updated as well and the redirect will go thru, unless you put in some kind of error checking. rm --- Somazx Interesting <somazx@home.com> wrote: > > I'm running into this really odd, seemingly > illogical problem: > > > Background: > > This is an on-line course made up of lots of pages, > some have forms, some > don't.
