Norton Safe Web: Site Verification

I am trying to verify my site www.rpjl.co.uk but am having difficulties.  I am using a site builder and do not have access the root folder.  I tried to add the verification file in the keywords area of the home page of the website following the instructions, but it does not seem to have worked.  I wonder if someone could help me with this. I appreciate your time and efforts and look forward to hearing from someone soon....

This is what I have added to the keywords:

<head>
<title>Title text</title>
<meta name=”norton-safeweb-site-verification” content=”string I received”/>
</head>
<body>
. . .
</body>
