Page Background Missing in Firefox and Chrome

Can anyone help please? On my first attempt at a WordPress website – www [dot] quickhomesalesuffolk.co.uk/blog/ – I cannot seem to get the background for the main sidebar+content section to appear in firefox or chrome (it works fine in ie).

At the very end of the header.php file, I have

</div>
<div id=”page”>

and at the start of the footer.php file I have:

<hr />
</div>
<div id=”footer”>

then in my style.css I have:

#page {
margin: 0px auto;
padding: 0;
width: 950px;
background-color: white;
background: url(‘images/etica-contentb.gif’) repeat-y;
z-index: 100;
}

IE 6 and 7 both show the etica-contentb.gif image repeated vertically down the length of the sidebar+content section; firefox and chrome just show the grey body background image.

What is likely to be causing this?

Is there an alternative way of getting a sidebar+content background image (note this image must go the entire length of BOTH sections).
