Sum of the count column

Transact-SQL
1

HI All,

I have below Query and need to get the sum of the "count" column? looks like the [Total counts/User], column count is not right in this case I should get total count of 25 not 19.
Thanks!

select
count(c.modified_by) over (partition by ndc_id ) as count,
sum(count(medication_name))over (partition by c.created_by) as [Total counts/User],
from medication.

medicaton_name =varchar (70)
ndc_id=char(11)
meds_count
