<!--
// === COMMON TEMPLATE (SAME FOR ALL SHOPPING SITES) ===
// Version 1.86
// (SS,25/6/09) version numbering started, new function itp_onload
// (SS,26/6/09) refined rd= functionality
// (SS,13/8/09) minor change to function itp_do_rd
// (SS,9/12/10) added functions itp_SetGridWidth, getInternetExplorerVersion, isIE, doResize
// for new grid width fitting feature
// (SS,07/06/11) added function itp_ConfirmMessage() and itp_checkout_bypass()
// (SS,17/06/11) recent change had caused call to itp_ConfirmMessage and itp_checkout_bypass() routine to go missing, added back in
// (SS,11/07/11) fixed frmSearch issue in FireFox by using getElementById, prefixing with document would also have worked
//               issued was caused by new DOCTYPE used, fine in all other browsers
//               removed itp_getwindowsize
// (SS,15/07/11) added alert to function itp_buyo
// (SS,22/07/11) removed itp_popupPicture, no longer used
// (SS,25/07/11) minor fix to itp_Currency()
// (SS,06/10/11) for VAT validation added functions itp_checkout_submit, itp_accounts_submit, itp_validate_vat, itp_validate_vat_callback
