Hello,  i just bought a Sticker plugin from you. It is fantastic and i really good. I am currently evaluating the Simple checkout and i have a question. I use the Norton Shopping guarantee program and they need the below code. Can you please help what need to be filled ?

_GUARANTEE.Guarantee.order = 'Checkout.OrderNumber';
_GUARANTEE.Guarantee.subtotal = 'Checkout.Total';
_GUARANTEE.Guarantee.email = 'Checkout.Email';
_GUARANTEE.WriteGuarantee('JavaScript', '_GUARANTEE_GuaranteeSpan');

===============================================

<!-- BEGIN: NSG_GUARANTEE -->
<span id='_GUARANTEE_GuaranteeSpan'></span>
<script type="text/javascript" src="//nsg.symantec.com/Web/Seal/gjs.aspx?SN=*********"></script>
<script type='text/javascript'>
if(window._GUARANTEE && _GUARANTEE.Loaded) {
_GUARANTEE.Hash = '**********************';
_GUARANTEE.Guarantee.order = 'Checkout.OrderNumber';
_GUARANTEE.Guarantee.subtotal = 'Checkout.Total';
_GUARANTEE.Guarantee.email = 'Checkout.Email';
_GUARANTEE.WriteGuarantee('JavaScript', '_GUARANTEE_GuaranteeSpan');
}
</script>
