Does this js need to be in the header?
<script type="text/javascript">
<!--
var number_format_dec = '.';
var number_format_th = '';
var number_format_point = '2';
var store_language = 'US';
var xcart_web_dir = "";
var images_dir = "/skin1/images";
var lbl_no_items_have_been_selected = 'No items have been selected';
var current_area = 'C';
-->If so where is it at to link to it instead of it being on each page? I have tried to remove it and link to it but I get errors.
