How can I make submenu corners round

Hello,

Submenu in arquitecture template has the corners square (90° angle). We need the corners round, how can I get the submenu had corners round.

I'm sending a picture showing what I mean.

Would you give me an advice?

template_css.css:

#nav > li {
float: left;
position: relative;
margin: 0 10px 0 0;
height: 50px;
-moz-border-radius-topleft: 12px;
-webkit-border-top-left-radius: 12px;
-moz-border-radius-topright: 12px;
-webkit-border-top-right-radius: 12px;
-moz-border-radius-bottomleft: 12px;
-webkit-border-bottom-left-radius: 12px;
-moz-border-radius-bottomright: 12px;
-webkit-border-bottom-right-radius: 12px;
border-radius: 12px 12px 0 0;
behavior: url(templates/hot_architecture/css/PIE.php);
}

remove properties I marked bold

Hello again,

Maybe I didn't express well my idea.

My boss asked the corners in the page were always rounded, not squared.

The hotel template is a good example of we need.

We would needed the style of hotel template's top menu but applied to arquitecture template.

(I tried to copy the css of top menu from hotel template to arquitecture template but it was a mess and I didn't get the rounded corners effect).

I'm sending pictures trying to be more clear.

Thanks in advance.

then it is:

#nav ul{
-moz-border-radius-topleft: 12px;
-webkit-border-top-left-radius: 12px;
-moz-border-radius-topright: 12px;
-webkit-border-top-right-radius: 12px;
-moz-border-radius-bottomleft: 12px;
-webkit-border-bottom-left-radius: 12px;
-moz-border-radius-bottomright: 12px;
-webkit-border-bottom-right-radius: 12px;
border-radius: 12px 12px 0 0;
behavior: url(templates/hot_architecture/css/PIE.php);
}

I appreciate your answer, but I applied the changes you send me but nothing happens. Submenu is still squared, not rounded.

Could you give me another advice? (I applied the changes in local server to try them and not in production server so you wont see the changes in my online version now).
