// This script supports an unlimited number of linked combo boxed
// Their id must be "combo_0", "combo_1", "combo_2" etc.
// Here you have to put the data that will fill the combo boxes
// ie. data_2_1 will be the first option in the second combo box
// when the first combo box has the second option selected

window.onload = function () {
	//get a reference to the second comboBox.
	var currentCOMBO = document.getElementById("combo_1")
	//Check to see if it has a null value (false) - if so that means were dealing with I.E., so refresh the page.
	if (!currentCOMBO.value) { 
		window.location = window.location; // on reload the currentCombo.value = 1. No idea why.
	};
