T-SQL Pivot multiple columns duplicates results - sql-server

Question

I have a table with aggregated data that I would like to pivot. Here is a sample of the data:
Unit# EffectiveDay RequestCount ResponseCount
5 1 0 0
5 2 8 8
5 3 4 4
5 4 4 4
5 5 2 2
5 6 0 0
5 7 2 2
6 1 0 0
6 2 0 0
6 3 0 0
6 4 0 0
6 5 0 0
6 6 0 0
6 7 0 0
I can successfully pivot the RequestCount column, but when I add the ResponseCount column it's as if the rows increased exponentially. Instead of two rows (one for each unit#), I get 14.
select *
from (
select Unit#
,concat('Request', EffectiveDay) AS RequestDay
,RequestCount
,concat('Response', EffectiveDay) As ResponseDay
,ResponseCount
from #tmpLogPayConnexion
) as P
pivot (
sum(RequestCount)
for RequestDay in ([Request1], [Request2], [Request3], [Request4], [Request5], [Request6], [Request7])
) as pvtRequest
pivot (
sum(ResponseCount)
for ResponseDay in ([Response1], [Response2], [Response3], [Response4], [Response5], [Response6], [Response7])
) as pvtResponse
I know this is possible, but I am stumped.
Thank you.

This seems like a time for a crosstab, or conditional aggregation.
select [Unit#]
, Request1 = max(case when EffectiveDay = 1 then RequestCount end)
, Request2 = max(case when EffectiveDay = 2 then RequestCount end)
, Request3 = max(case when EffectiveDay = 3 then RequestCount end)
, Request4 = max(case when EffectiveDay = 4 then RequestCount end)
, Request5 = max(case when EffectiveDay = 5 then RequestCount end)
, Request6 = max(case when EffectiveDay = 6 then RequestCount end)
, Request7 = max(case when EffectiveDay = 7 then RequestCount end)
, Response1 = max(case when EffectiveDay = 1 then ResponseCount end)
, Response2 = max(case when EffectiveDay = 2 then ResponseCount end)
, Response3 = max(case when EffectiveDay = 3 then ResponseCount end)
, Response4 = max(case when EffectiveDay = 4 then ResponseCount end)
, Response5 = max(case when EffectiveDay = 5 then ResponseCount end)
, Response6 = max(case when EffectiveDay = 6 then ResponseCount end)
, Response7 = max(case when EffectiveDay = 7 then ResponseCount end)
from #tmpLogPayConnexion
group by [Unit#]
order by [Unit#]
