only list certain fields in output query until those fields are selected, then auto show next fields

this is a doozy -

my db table lists timeslots:

eg
02/04/2004 08:30:00
02/04/2004 9:00:00
02/04/2004 9:30:00
02/04/2004 14:00:00
02/04/2004 14:30:00
02/04/2004 15:00:00

02/05/2004 08:30:00
02/05/2004 9:00:00
02/05/2004 9:30:00
02/05/2004 14:00:00
02/05/2004 14:30:00
02/05/2004 15:00:00

etc

my client wants the webpage to show only the 1st am and pm slots until they're "taken" then wants to auto show the next in line so:

1st:
02/04/2004 08:30:00, 02/04/2004 14:00:00
02/05/2004 08:30:00, 02/05/2004 14:00:00

then when these are deleted (they get deleted from the table when they are "taken)

show the next 2:

02/04/2004 09:00:00, 02/04/2004 14:30:00
02/05/2004 09:00:00, 02/05/2004 14:30:00

here's my existing code:

<cfquery name="rsTimes" datasource=#MM_connCalArts_DSN# username=#MM_connCalArts_USERNAME# password=#MM_connCalArts_PASSWORD#>
SELECT count(*) as slotsremain,  timeslots_theater.timeslots, mix_theater.cities_id, cities_theater.cities,
mix_theater.timeslots_id, mix_theater.mix_id, timeslots_theater.id FROM timeslots_theater,
mix_theater, cities_theater WHERE timeslots_theater.id = mix_theater.timeslots_id
AND cities_theater.id = mix_theater.cities_id AND cities_id = '#rsTimes__MMColParam#'
group by timeslots
order by timeslots asc
</cfquery>
