JavaScript and CSS3 Border Radius

[The Little Guy]

I am using JavaScript to render some css3 the problem that I am having is that it isn't working...

 

Here is the JavaScript:

if(tabid > 0){
result.setAttribute('class', 'btlradius');
}

 

.btlradius{
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
}

 

it all works, but for some reason it don't change the border radius, why is that? If I were to add:

 

color:#FF0000;

 

It changes the text's color, but the border radius doesn't change why?

 

Here is an example:

if you click on Health the radius doesn't change for where the results display.
