Form Validation Errors Showing HTML Code on Hover

Greetings fellow Site Point forum members!

I’ve just encountered a problem that after 6+ years of web designing, I have never encountered before.

I have a form that has a few of it’s fields being validated with JavaScript. When you attempt to submit this form without those fields being filled out, the form pops up some error messages in red divs that let the user know that they need to fill out those fields.

So far so good.

HOWEVER, When you hover your mouse over these error message, browsers are showing the HTML code that I have used to create them.

I have attached a screenshot of the issue, and here is a link to the page that is causing the problem.

Does anyone know why this is happening, and what I can possibly do about it?

Thanks in advance!

Mkto.setError = function(fld, message) {
  fld.parentNode.className += " mktError";
[COLOR="#FF0000"]  fld.parentNode.parentNode.title = message;[/COLOR]
  var msgContainer = Mkto.getMessage(fld);
  msgContainer.innerHTML = message; = (fld.parentNode.offsetWidth + 10) + "px";
  Mkto.addListener(fld, 'focus', Mkto.clearOnClick);

I would say it’s the highlighted line that’s doing that.
