Type problem in erlang?

Hi!

I have a problem with the dets module. The function match(Name, Pattern) is giving me trouble. I have a dets table that stores records
with 8 elements. Here is a code section to describe the problem:

LocId = 1323,
dets:match(TableId, {‘_’,’_’,LocId,’$1′,’_’,’_’,’_’,’_’,’_’}).

This does not work and returns an empty list. But the following works:

dets:match(TableId, {‘_’,’_’,1323,’$1′,’_’,’_’,’_’,’_’,’_’}).

Why is that? LocId = 1323 and should work as well?

Another question:
When a list of integers is returned
they sometimes change type to ASCI.

Ex:
[[7],[9],[10]]
is returned as:
[” “, /s, [10]]

can this be prevented?
