Count Need To Bring Back A Zero When No Matches

I am trying to do a calculation with the below query and it works long as d.closegoal has values and d1.opengoal has values but the problem is when there is no count for either, I need to bring back a value of zero if there are no matches. Since I am using it in an outer select statement for a calculation it not bringing anything back because of no matches.
This is my code:

select d.lwia,

cast((d.closegoal + d1.opengoal) as float)denominator

from

(

select yg.lwia,

cast(count(yg.appid)as float) closegoal

from dbo.wiayouthgoals yg

where yg.lwia = @RWB

-- Attained a goal in the timeframe timely or untimely

and ((convert(smalldatetime, convert(varchar(10),yg.youthattaindate, 101)) >= @BeginDte -- Parm date for beginning of time frame needed

and convert(smalldatetime, convert(varchar(10),yg.youthattaindate, 101)) <= @EndDte) -- Parm date for end of time frame needed

-- Goal due but not attained

or (convert(smalldatetime, convert(varchar(10),yg.youthgoalanniversary, 101)) >= @BeginDte -- Parm date for beginning of time frame needed

and convert(smalldatetime, convert(varchar(10),yg.youthgoalanniversary, 101)) <= @EndDte -- Parm date for end of time frame needed

and yg.youthattaingoal <> 1))

group by yg.lwia

)d,

(

-- Closure with open goal

select cast(count(yg.appid)as float) opengoal

from dbo.tbl_caseclosure cc,

dbo.wiayouthgoals yg

where yg.appid = cc.col_idnum

and convert(smalldatetime, convert(varchar(10),cc.col_closuredate, 101)) >= @BeginDte -- Parm date for beginning of time frame needed

and convert(smalldatetime, convert(varchar(10),cc.col_closuredate, 101)) <= @EndDte -- Parm date for end of time frame needed

and yg.youthattaindate is null

and yg.lwia = @RWB

group by yg.lwia

)d1

)d2
