[erlang-questions] Comparing tuple records in MatchSpec

Hi,
i have mnesia table which stores date in tuple format {Y,M,D}, 
To fetch data that falls on given date frames I tried to use this record
MatchSpec = [{#appointment{id='$1', starttime = '$2', endtime = '$3',  _='_'},                        [{'orelse',{'>=','$2',StartTime},{'orelse',{'=<','$3',EndTime}}}],                        ['*']}] 
where Startime and Endtime are records. This throws and bad arg during transaction.
But when I change the Startime and End time as integer or list it executes without any problem.
Is this the normal behaviour, or am I missing out anything, Any work around to achieve this?
Thanks,Marutha
