Can not get SSL Seal code to install

Hi,

I want to install SSL Seal from Comodo on Scribe but it refuses to accept it. The code is in 2 parts:

1. Add this before your </HEAD> tag
<script type="text/javascript"> //<![CDATA[
var tlJsHost = ((window.location.protocol == "https:") ? "https://secure.comodo.com/" : "http://www.trustlogo.com/");
document.write(unescape("%3Cscript src='" + tlJsHost + "trustlogo/javascript/trustlogo.js' type='text/javascript'%3E%3C/script%3E"));
//]]>
</script>

2. Add this before your </BODY> tag
<script language="JavaScript" type="text/javascript">
TrustLogo("https://www.triple-grace.com/wp-content/uploads/2017/03/comodo_secure_seal_113x59_transp.png", "CL1", "none");
</script>
SSL Certificates

Can somebody help me to install it?
