'go' button location change

[MonteChristo]

i am rather new to javascript. what i am trying to create are three dropdown menu fields - Region Select, Country Select and Language Select, followed by a 'Go' submit button. i have it working to the point where each option is greyed out until you make a selection from the previous dropdown. what i cant figure out is how to make the 'go' button load various pages depending on the previous dropdown choices. (for example if the user selects north america and canada and english, then when the go button is hit, that particular html page would load up.

i have attached my .html and my .js files if anyone is interested! thanks.

anybody have any ideas? my html file loads in my external .js file. the javascript is as follows:



function fillCategory(){
// this function is used to fill the category list on load
addOption(document.drop_list.Category, "NAmerica", "North America", "");
addOption(document.drop_list.Category, "LAmerica", "Latin America & Caribbean", "");
addOption(document.drop_list.Category, "Africa", "Africa", "");
addOption(document.drop_list.Category, "Europe", "Europe & Middle East", "");
addOption(document.drop_list.Category, "Asia", "Asia Pacific", "");
}

function SelectSubCat(){
// ON selection of category this function will work

removeAllOptions(document.drop_list.SubCat);
addOption(document.drop_list.SubCat, "", "COUNTRY SELECT", "");

if(document.drop_list.Category.value == 'NAmerica'){
addOption(document.drop_list.SubCat,"USA", "United States");
