Case When

Hi all. what is wrong with my query?

DECLARE @empDcno varchar(20), @secnum int
set @empDcno = '205'
set @secnum = 1

select l.* , e.paytype
from hrempleaveledger as l
inner join hremployees as e on l.empdcno = e.empdcno
inner join hrsetbenefitsleave as b on l.type = b.type
inner join mscsections as s on e.sectioncode = s.sectioncode
inner join mscdivisions as d on e.divisioncode = d.divisioncode
inner join mscbranches as br on e.branchcode = br.branchcode
inner join CSVTable(@empDcno) as R on e.empdcno = R.stringval
where e.sectioncode =
case @secnum
when 1 then '1001'
when 2 then '1002'
else ''
end

did i use the case/when statement properly? if not, how could i query this in correct format?
