I have two drop/down menus that are dependant on each other. When I have
made a choice in both of these menus and press a button I get to a page
depending on the choice made. On this page there is two buttons "Accept"
and "Back".
When I press "Back" I would like to get back to the page with the two
menus and they should be set to the choice I made. Now the just reset when I
press the "Back" button.
Is it possible to save the options that I choose from the drop/down menus
when I get back to them by pressing "Back"??
Here's one solution. Watch for word-wrap.

var ind2 = form.sel2.selectedIndex;
if (ind1 == 0 || ind2 == 0) return false;
var sel1 = form.sel1.options[ind1].value;
var sel2 = form.sel2.options[ind2].value;
document.action += "?" + sel1 + "&" + sel2;
return true;
}
function selects() {
var qstr = location.search;
if (qstr.length < 4) {
alert("Invalid QueryString!");
return;

var form = document.form1;
qstr = qstr.substr(1);
var pair = qstr.split("&");
for (var i=0; i<pair.length; i++) {
var item = pair[i].split("=");
if (i == 0) {
