TOPIC: Sign Up

03.) Sign Up:

-When a user signs up for an event, I need the ability to have additional
"options" for the event. For instance, during the sign up process for the
"Main Convention", an option might be: Are you signing up for individual
days or the entire event. In our case there are 4 days. The entire event
if registering before a certain date would cost $45.00, if after a certain date, the cost is $50.00. If someone selects that they are signing up for individual days, then they are given a list of days/dates
(Thur/Fri/Sat/Sun). They can check the days they want to attend. Each day
is $25.00 per day. If they checked all 4 days, and the time they are
signing up is "pre reg", then it would still only cost the user $45.00 not $100.00 (why the user would do this I don't know, but just in case).

Also,someone that selects to sign up for the "entire" event, then it auto
selects all 4 days (as options).

Currently the only way to do this with custom fields, will NOT give the
ability to check prerequisites against a day like Fri. So I need a single
"Main Event" listing of users, but with "options/days". Then the
"Prerequisites" checking can be set to check theses options as well (see
next section)
