using php to call for different styles?

Hey Guys,

I am trying to code a wordpress site, and I am using the following php statement in the <style></style> but for some reason it isn't working. Like, it understands it, and if I look at the source, it puts out what it's supposed to put out, but it doesn't intergrate it into the page or the css. Any clue why? Or should I be asking this on the css/html forum?

body { background-image:<?php if (is_front_page()) { 
echo "url(images/bg-front.png)";
}
else { "url(images/bg.png)";
} ?>;

PHP:

It only doesn't work when I try to put in an image. If I for example do background-color: or width: it works.

Any help will be appreciated.

Regards,
Nick
