Lite strul med en combo drop down

[G8]

Hej,

har lite strul med detta script. När man gjort sitt val så skickas man vidare till en sida för att validera sitt val. Om man då väljer att gå tillbaka till den ursprungliga sidan med combo boxarna så blir den andra boxen tom, behåller alltså inte det aktuella valet. Den Finns det något sätt att behålla värdet på det val man har gjort (dropdown #2), eller någon annan lösning?

Tänkte man kanske kunde köra med en session i ASP för att hålla reda på vilket val man har gjort och sedan populera den andra dropdownen med hjälp av värdet i session. Någon som har något annat bättre förslag?

Testa att lägga till följande innanför <script>-taggarna:[kod]window.onload=function(){
SkapaVal(document.forms["val"].elements["huvud"].selectedIndex);
}[/kod]
