[SOLVED] Rounded corners - im just not getting it

On previous sites, I wanted straight edges and got rounded corners and couldnt get rid, now I want rounded corners I cant seem to get them.

I uploaded the rounded setting file, and made a few changes as I couldnt see any rounded corners

Now Im trying to get my page menu with rounded edges and I cant seem to get it done, any advice is welcome:

website: test.mentorg dot co.uk

I;ve added the following into ATO: css/html but i must be doing something wrong


#rmenu2 li {
padding: 10px 0px;
}


/* round corners for page menu bar items */
#rmenu2 li {
-webkit-border-top-left-radius: 25px;
-webkit-border-top-right-radius: 25px;
-moz-border-radius-topleft: 25px;
-moz-border-radius-topright: 25px;
border-top-left-radius: 25px;
border-top-right-radius: 25px;


Any other tips for rounded corners in the other aspects wuld be much appreciated too, as I've copied code from here all afternoon and I just cant seem to get it all working
