Background repeat all the way down column

Hi,

Can anyone tell me if there is a way to get my background image of my right hand column (sidebar-b) to repeat all the way down as far as the length of my central column....?

This is how I have it at the mo....:

#sidebar-b {
float: right;
width: 200px;
\width: 210px;
w\idth: 200px;
margin: 0;
margin-left: 5px;
padding: 5px;
background-image: url("images/bluefadehoriz.gif") 0 0 repeat-y;
}

This is what you need:
