My background is not staying in my set position Options

[x3chrissyx3]

Here is a sample of my bg code:
<style type="text/css">
body {
background-color: 000000;
background-image: url('http://i9.tinypic.com/8f50cvl.jpg');
background-attachment: fixed;
background-repeat: no-repeat;
background-position:b ottom left;
}

and all it does is go to the top right. I have tried the variation "bottom-left" and it did nothing. I am using Firefox. Wtf is up? haha
