SQL & PL/SQL :: Decode With Between Clause

I have a small doubt...Without any creation of tables as I feel it's not needed...(let me know if u need them) Error says "Missing Keyword"

select distinct record_number
from meta m, procedu b, control v, fact f, calendar dc, person p
where f.key = m.key and f.group_key = b.group_key
and b.proc_key = v.proc_key
and f.calendar_key = dc.calendar_key
and f.person_key = p.person_key
and VALUE BETWEEN DECODE((Select distinct operator_type
[code]....

But this gives an error...If the decode gives a "single"...the statement is working fine...but If the decode gives a "range"...the above statement gives an error saying "missing keyword"..Does the above code when mapped to "Range"...is it not producing "and" like " value between 100 and 1000"
