Can you see if @font-face is working?

Hello there,

My blog is http://www.echofestival.com and I am using the @font-face code in my css style sheet so that I can used the font Zag Bold. Various people have already told me that they cannot see the font, which I am using in all of my headers h1, h2, h3 and h4 – is the problem here? How I declare it?

Could you tell me if it is visible? I am using firefox but some people cannot see it…

The code I am using is

@font-face {
font-family: ‘ZagBoldRegular’;
src: url(‘http://echofestival.com/fonts/zag_bold-webfont.eot’);
src: url(‘http://echofestival.com/fonts/zag_bold-webfont.eot?#iefix’) format(’embedded-opentype’),
url(‘http://echofestival.com/fonts/zag_bold-webfont.woff’) format(‘woff’),
url(‘http://echofestival.com/fonts/zag_bold-webfont.ttf’) format(‘truetype’),
url(‘http://echofestival.com/fonts/zag_bold-webfont.svg#ZagBoldRegular’) format(‘svg’);
font-weight: normal;
font-style: normal;
