SQL - Issue with Having and Grouping - mysql

Question

Hi I'm having an issue with a query that was once working. My SQL skills aren't all that great, not sure what I'm missing. Or if this is the correct approach. Maybe use a temp table instead?
The basic gist is given a certain time frame, I need to calculate the highest aggregate of points over 5 classes.
trialScores - keeps scores/points,
trials, dog, people and member tables are just meta data
classId 5 requires a different date range
Here is my Query on MySQL
select
t.id,
d.id,
p.id,
p.firstname,
p.lastname,
d.id dogId,
d.dogName,
c.id,
c.class,
t.trialStartDate,
s.points,
if(c.id = 5, '2012-08-01', '2012-11-18') as startDate,
if(c.id = 5, '2013-07-31', '2013-12-31') as endDate,
SUM(ts.points) AS pointsAggregate
from trialScores ts
inner join trials t on t.id = ts.trialId
inner join dogs d on d.id = ts.dogId
inner join people p on p.id = ts.personId
inner join classes c on c.id = ts.classId
where t.deletedAt is null
and ts.deletedAt is null
and ts.memberAtTrial = 1
and d.omitFromTripleCrownDOY = 0
and t.associationId = 1
GROUP BY p.id, ts.dogId, ts.classId
having t.trialStartDate between startDate and endDate
order by ts.classId, pointsAggregate desc
Looks like this fixed it, too much in the select and not in Group by?:
select
d.dogName,
c.class,
p.firstName,
p.lastName,
SUM(ts.points) AS pointsAggregate
from trialScores ts
inner join trials t on t.id = ts.trialId
inner join dogs d on d.id = ts.dogId
inner join people p on p.id = ts.personId
inner join classes c on c.id = ts.classId
where t.deletedAt is null
and ts.deletedAt is null
and ts.memberAtTrial = 1
and d.omitFromTripleCrownDOY = 0
and t.associationId = 1
and t.trialStartDate between if(c.id = 5, '2012-08-01', '2012-11-18') and if(c.id = 5, '2013-07-31', '2013-12-31')
GROUP BY ts.dogId, ts.classId
order by ts.classId, pointsAggregate desc

Can you try below query and let if it's work or not ?
select
d.dogName,
c.class,
p.firstName,
p.lastName,
SUM(ts.points) AS pointsAggregate
from trialScores ts
inner join trials t on t.id = ts.trialId
inner join dogs d on d.id = ts.dogId
inner join people p on p.id = ts.personId
inner join classes c on c.id = ts.classId
where t.deletedAt is null
and ts.deletedAt is null
and ts.memberAtTrial = 1
and d.omitFromTripleCrownDOY = 0
and t.associationId = 1
and t.trialStartDate between if(c.id = 5, '2012-08-01', '2012-11-18') and if(c.id = 5, '2013-07-31', '2013-12-31')
GROUP BY ts.classId,p.firstName,p.lastName
order by ts.classId, pointsAggregate desc
