On your main page you have some text "Independent/Group Tours" half way down the page, so as an example say you want to jump down to it, you'd give the text a name using the Anchor tag (<A>). i.e.
<A NAME="igt">Independent/Group</A> Tours
Next create a hyperlink(s), say on left pane menu and reference it to the named tag above. i.e.
<A HREF="#igt">Independent/Group Tours</A>
or if your on another page on within your site and would like a reference to it just hyperlink to it as you normally would but include the tag name. i.e.
<A HREF="home.htm#igt">Independent/Group Tours</A>
and the same goes if I wanted to hyperlink/reference to it from my site I would just include the full address. i.e.
<A HREF="http://yoursite/home.htm#igt">Independent/Group Tours</A>
By the way, you need to turn the menu frame scrolling to "on" or "yes" as the menu scrolls of the bottom of the screen, well thats for 800x600 dpi res anyway and I took a look at the source code of your menu pane "menu.htm" and saw how repetative the tags were, you could vertually cut the code size in half, cutting the file size in half also, using css which I copyed and added to, Shaun may see what I mean or is this to do with that Microsoft Crap "FrontPage".
