this code should stop people from going forwards
Code:
<script type="text/javascript">
function validateSelections()
{
var dropDown1 = document.GetElementByID(yourDropDown1)
var dropDown2 = document.GetElementByID(yourDropDown2)
var sIndex1 = dropdown1.selectedIndex;
var sIndex2 = dropdown2.selectedIndex;
if(dropdown1.options[sIndex1].text == "" || dropdown2.options[sIndex2].text == "")
{
alert("Select an option from both please...");
}
}
</script>
Remember to give your <select></select> tags an id with yourDropDown1 and yourDropDown2 or choose your own
That works for me, but i still think you should definitly be using XML/DB to be populating menu's and PHP caters for this i am sure. However, I don't do PHP so couldn't help you with that bit.
