Urgent: Sub-menu DIV fades off before I'm on it.

Urgent: Sub-menu DIV fades off before I'm on it.

Hi

I'm using this code to display a sub-menu when over a level one menu:

$("li.services").hover(function(){
$('#events_subnav').fadeIn();
},function(){
$('#events_subnav').fadeOut();
});

The only problem is that when I move away from the top menu button, sub-nav that was displayed on hover goes off too.

I would appreciated any quick help.

Many thanks.
