Help with Updating Page

Question

Hi, I have inherited the updating of our website. I am trying
to edcuate myself about Dreamweaver, CSS and HTML with as much
reading of books, online material like this forum and tutorials. I
am a novice with limited training in DW, but am willing to put in
the work. I think I have a big burden.
This site was created in FrontPage by an outside firm and was
transferred to DW in house (I think).
Documentation is about non-existent beyond web host info and
passwords. I don't think it was considered that certain pages
within the site would be edited. I am trying to understand what is
going on in the code, but I am baffled.
I am trying to edit the dropdown menu to remove one location,
New York.
When I delete what I think are the appropriate lines of code,
the remaining items in the menu fail to display the correlating
info in the text area and in the image area on the right side of
the page.
This is the page;
http://www.wesgarde.com/branches.shtml
Can anyone help me get that one location removed, along with
making the rest of the menu items fall into place?
Appreciate any info,
Thanks, Michele

The problem is that the Add-ons Manager tab when opened the first time, is on "Get Add-ons" section and that must be downloaded from the Add-ons server which might be overburdened.
* If you need to look for new Add-ons, go directly to the Add-ons site -> https://addons.mozilla.org/en-US/firefox/
Perform the suggestions mentioned in the following articles:
* [https://support.mozilla.com/en-US/kb/Template:clearCookiesCache/ Clear Cookies & Cache]
* [[Add-ons are disabled after updating Firefox#w_check-for-new-versions-of-your-add-ons|Check for New versions of your Add-ons]]
Check and tell if its working.
Not related to your problem but some of your Plugins are out-dated
* Update All your Firefox Plugins -> [https://www.mozilla.org/en-US/plugincheck/]
