Dreamweaver Jump Menus help please

[charter]

I have 10 pages to connect on my website to Jump Menus

One Menu has 2 selections UK and USA
The second menu has a choice of 5 selections - 1960 - 1970 - 1980 - 1990 - 2000.

Eventually there will be more pages to add with more countries and more years.

I wish to link them to the pages uk60.htm - uk70.htm and so on and the same with US pages which are us60.htm - us70.htm and so on.

Can someone please tell me how to code the links so that, for example if someone selects USA on the first menu and then 1980 on the second menu then when the GO button is clicked will open the page us80.htm ?

The coding I have for the menus is

<form name="form1">
<select name="menu1" onChange="MM_jumpMenu('parent',this,0)">
<option selected>UK</option>
<option>USA</option>
</select>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<select name="menu2" onChange="MM_jumpMenu('parent',this,0)">
<option selected>1960</option>
<option>1970</option>
<option>1980</option>
<option>1990</option>
<option>2000</option>
</select>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<input type="submit" name="Submit" value="Go">
</form>

It's just that I don't know how or where to put in the appropriate links in the coding on a multple menu.

To view the links page I have it is http://www.worldcharts.co.uk/links.htm HERE

When I can get these links sorted out, I will then intgrate it into a full web page.

I have looked in several Dreamweaver books but they only show how to connect a single menu which I already know.

All help would be very much appreciated
