Sure, use this JavaScript
first, create a hidden field on your form. Then, use the following event on the OnChange of the SELECT object:
for giving it the value of the VALUE option:
document.FORM.the_hidden_field.value = document.FORM.select.selectedIndex;
for giving it the value of the text of the option:
document.FORM.the_hidden_field.value = document.FORM.select.value;
Hope it helps
