rounded corners

I would like to get the rounded corners correct in IE browsers, I have found the next information but still get it not working. Can anyone help me out?

Code: Select all

.box_text>div>div { background:#fff; padding-bottom: 0px; ;
     -moz-border-radius: 20px;
    -webkit-border-radius: 20px;
    -khtml-border-radius: 20px;
    border-radius: 20px;
    behavior: url(/css/border-radius.htc);
    border-radius: 20px;
    border: 3px solid #dbb2e0
}

#gkComponent > div > div {
 background:#fff; padding-bottom: 0px; ;
     -moz-border-radius: 20px;
    -webkit-border-radius: 20px;
    -khtml-border-radius: 20px;
    border-radius: 20px;
    behavior: url(/css/border-radius.htc);
    border-radius: 20px;
    border: 3px solid #dbb2e0
}

I have used this for the browsers except in IE it will not work...
