Using Fireworks JS menu in Dreamweaver

Web Site: http://www.newbabyproducts.com

Converting site from FrontPage to Dreamweaver. Wanted to have a drop down
menu that I could easily update (or have someone in the office update) without
having them to know much about Dreamweaver or Fireworks. I do not mind doing
this myself - but want to keep the process simple. This menu is for a store
and will be updated on a regular basis.

When I placed the initial fireworks html I made one big mistake. I did not
set it up using a template.

I have since tried putting the menu into a Library file that I could go back
and insert into all 170-some-odd pages, but the menu does not seem to work on
the pages I have tested it on (I always get a runtime error).

What (if any) options do I have to be able to use a menu from Fireworks that I
can update on a regular (bi-weekly) basis without having to reinvent the site
each time.

I'm sure that there must be something out there that as a newbie I am
completely clueless on.

Thank you all in advance for you help.
