Add a param to SQL query

Question

I have a sql statement i would like to parameterize.
How do i add params to the statement for Start and End Dates and Also hostalias
hostalias maybe multi-value  :-
SELECT srmhosthost.hostname hostnamehost,
srmfilesystemfilesystem.fsmountpoint
fsmountpointfilesystem,
srmfilesystemfilesystem.filesystemdevice
filesystemdevicefilesystem,
srmfilesystemfilesystem.resideson
residesonfilesystem,
ROUND(max
(fsmetricsmonthlyfilesystem.fsusedmax/1048576), 5)
max_used_GB,
Round(max
(fsmetricsmonthlyfilesystem.fstotalmax/1048576), 5)
file_system_size_GB,
Round(min
(fsmetricsmonthlyfilesystem.fsusedmax/1048576), 5)
min_used_GB,
Round(avg
(fsmetricsmonthlyfilesystem.fsusedmax/1048576), 5)
avg_used_GB
FROM srmhost srmhosthost, hostmetricsmonthly
hostmetricsmonthlyhost, srmudfinstance udfhostshost,
srmfilesystem
srmfilesystemfilesystem, fsmetricsmonthly
fsmetricsmonthlyfilesystem, srmudfinstance
udfhostsfilesystem, srmdate
WHERE (srmhosthost.iscurrent = 'Y' OR
srmhosthost.iscurrent IS NULL) AND
srmhosthost.hostkey =
hostmetricsmonthlyhost.hostkey(+) AND
hostmetricsmonthlyhost.datekey = srmdate.datekey AND
hostmetricsmonthlyhost.datekey >=
(SELECT min(srmdate.datekey) from Srmdate srmdate
where srmdate.datestamp >= to_date ( '9/01/2009',
'MM/DD/YYYY' ) ) AND
hostmetricsmonthlyhost.datekey < = (SELECT max
(srmdate.datekey) from Srmdate srmdate where
srmdate.datestamp < = to_date (
'07/01/2010', 'MM/DD/YYYY' ) ) AND
srmhosthost.hostkey = udfhostshost.mokey(+) AND
(srmfilesystemfilesystem.iscurrent = 'Y'
OR srmfilesystemfilesystem.iscurrent IS NULL) AND
srmfilesystemfilesystem.filesystemkey =
fsmetricsmonthlyfilesystem.filesystemkey(+) AND
srmfilesystemfilesystem.filesystemkey =
udfhostsfilesystem.mokey(+) AND
srmhosthost.hostkey(+) =
fsmetricsmonthlyfilesystem.hostkey AND
hostmetricsmonthlyhost.datekey =
fsmetricsmonthlyfilesystem.datekey AND lower (
srmhosthost.hostalias ) in lower(
'apqmd508')
group by srmhosthost.hostname ,
srmfilesystemfilesystem.fsmountpoint ,
srmfilesystemfilesystem.filesystemdevice ,
srmfilesystemfilesystem.resideson

Hi Don,
     If i add the sql statement via ADD COMMAND, and create a param called "Host Names", which allows multile values.
I then changed the sql statement from :-
('appmd510')
to :
('{?Host Names}')
when i enter the the host name appmd510 and enter i get an ora-00907: missing right parenthesis
i want to be able to save the report, and then open, and only have to supply a start date/end date and host name(s)
if i do not create the param in the ADD COMMAND dialog box, and leave the sql statement with the ('{?Host Names}') in place
i do not get prompted for param. If i create a param(Host name)and in record selection  set Hostname  = {?HostNames}  i get nothing
