Time series problem - pls help

Hi! I need urgent help with a time series issue in vertica.
I am trying to create a time series query that will sum me bets per parameter given in a dashboard.
The only thing I have been able to do so far is to get the first or last value according to TS_FIRST_VALUE .I want to sum it , i don't want the first or last value.I am not able to do so.can you help me? My table is:
bets | time
--------+---------------------
2100 | 2020-09-25 01:00:00
212000 | 2020-09-25 01:00:01
1000 | 2020-09-25 01:00:02
3000 | 2020-09-25 01:00:03
11000 | 2020-09-25 01:00:04
..............................................(ofcourse I have tons of rows )
I need to create a time query where I want the bets to be summed up according to time parameter in the dashboard lets say 1 hour (but it can be any option like 15 min,30 min,1day...etc)
The only query I have been able to perform is this (there is a WITH clause before that filters the bet spins according other parameters ) and this is right after:

SELECT time, sum(first_bet) FROM (
SELECT slice_time as time, TS_FIRST_VALUE(filtered_bets) AS first_bet
FROM filtered_spins
TIMESERIES slice_time AS '1 hour' OVER ( ORDER BY time)
) AS result
GROUP BY time,result.first_bet Order by time;

it gives me this:
time | sum
