I'm having trouble getting my header background image to appear. This is the image I want at the top of the header: http://ogmda.com/test/img/top_grunge.png

Right now I have the CSS as:

Code:
header  {
	background-image: url(../img/top_grunge.png);
	background-position:top;
	background-repeat:repeat-x;
}
My live preview is here.

Anyone got any ideas? Seems like it may be clashing with #homeNav's background image logo ?
