[VE][105] Error Message Feedback

Validating http://theorniphile.info/
Error [105]: "an attribute specification must start with a name or name 
token"

I get this error message when I use javascript to scramble e-mail 
addresses. I've tried rewriting the code to make it work with the 
validator but no go. Here's an example of the code I use:

<p>Send comments to me, <script language="javascript" 
type="text/javascript">
var start = "<a href='mailto:";
var name = "rhughes.enteract";
var at = "@";
var url = "rcn.com?subject=re:Your birding Web site'";
var title = "title = 'E-mail me'>";
var link = "<span class='bold'>Robert Hughes</span>";
var end = "</a>";
document.write(start + name + at + url + title + link + end);
</script>.
</p>

Any suggestions?
