Is the order of the rules entered in iptables important?

Hello all.  I'm new to the list.  I have a quick question: does the order in
which rules are added for an iptables table matter?  I have a firewall that
has a pre-built iptables script that runs on boot.  Once the system boots,
I'm trying to add additional rules to the default chains but my rules are
not working.  I was wondering if that is because the boot script has, as
it's last rule, a DENY target and since it was "entered" before my new
rules, the DENY is always hit first.

Thanks in advance,
Kenny
