Gurgle... gurgle... attempting to compile. Ermm... guess I need to go back to DOM basics. Thanks for the point in the right direction.

place of the value property?
The cross platform way to get a value from a select box is as such:
form.elements.myselect.options[form.elements.myselect.options.selectedIndex]
.value
or likewise
temp = form.elements.myselect.options;
temp[temp.selectedIndex].value
You could write a function:
function selectValue(element)
{
return element.options[element.options.selectedIndex].value;
}
Then, simply use:
selectValue(form.elements.myselect)
Uggg.
In some cases, if you know the value you want to is option number 1, then
you can use simply
form.elements.myselect.options.selectedIndex == 0
If that is true, then you know that the first item in the dropdown is
selected.
