linear gradient in chrome and safari
===

Hi I am having trouble showing a linear gradient in safari / chrome. In Firefox it shows up fine...
I am trying.

    background: -o-linear-gradient(center top , #9E9E9E, #454545) repeat scroll 0 0 transparent;
	background: -moz-linear-gradient(center top , #9E9E9E, #454545) repeat scroll 0 0 transparent;
	background: -webkit-linear-gradient(center top , #9E9E9E, #454545) repeat scroll 0 0 transparent;
	background: -ms-linear-gradient(center top , #9E9E9E, #454545) repeat scroll 0 0 transparent;

thank you for your help.
