combining of two querys with grouping

My problem is I need to get the total (distinct) units built in a given time frame. see code

select areaid, count(distinct(serial_no)) as tested, case when wkid = 0 then datename(month,cast(cast(monthid as varchar(2))+'/1/1900' as datetime))
else 'Week ' + cast(wkid as varchar(2)) end as TimeBucket  from ##WhtBrds1147f
group by areaid, wkid, monthid, yearid

I also need to get the total number of defects even if a unit has multiple see code

select areaid,

cast(sum(fail)as int) as fail,

case when wkid = 0 then datename(month,cast(cast(monthid as varchar(2))+'/1/1900' as datetime))
else 'Week ' + cast(wkid as varchar(2)) end as TimeBucket,
0 as goal from ##WhtBrds1147f
where customer in ('HART') and areaid in ('FI')
group by  areaid, wkid, monthid, yearid order by yearid, monthid,areaid, wkid

Both work fine by them self but I need to get the tested and failed in to a single query to get the yield fail/tested grouped by areaid, wkid, monthid, yearid

I could do it by using temp tables... and requery it to get the answer but there has to be a better way.

what happens when you try this...

SELECT areaid,
   COUNT(DISTINCT(serial_no)) as tested,
   CAST(SUM(fail) AS int) AS fail,
      WHEN wkid = 0 THEN DATENAME(month,CAST(CAST(monthid as varchar(2))+'/1/1900' as datetime))
      ELSE 'Week ' + CAST(wkid as varchar(2))
   END AS TimeBucket
FROM ##WhtBrds1147f
GROUP BY areaid, wkid, monthid, yearid
