Google Fonts Font Doesn't load

Question

I'm trying to add PT Sans into a newsletter, but for some reason it isn't loading I've copied almost all of the code, but it isn't working. I would be so grateful for anyone who can help.

Here is the CSS code:

h1, h2, h3 {
    font-family: 'PT Sans', sans-serif;
}

and the HTML code:

<link href="http://fonts.googleapis.com/css?family=PT+Sans" rel="stylesheet" type="text/css">

EDIT: Here's the rest of the CSS:

h1, h2, h3 {
    font-family: 'PT Sans', sans-serif;
}

#logo{width:810px}

#saveDateText{
    position:relative;

Try to use URL without "http":

<link href="//fonts.googleapis.com/css?family=PT+Sans" rel="stylesheet" type="text/css">
