Navbar dropdowns not displaying over FCG - Agent 2.0

[Marc]

I would really appreciate any assistace or guidence.

I followed the instructions in this tutorial viewtopic.php?f=16&t=585 and changed the noted css code as follows.

Original css, this and this -

#nav li {
	float: left;
	list-style: none;
	margin: 0px;
	padding: 0px;
	}

#nav li li { 
	}

per tutorial became this and this -

#nav li {
	float: left;
	list-style: none;
	margin: 0px;
	padding: 0px;
   z-index: 15;
   position: relative;
	}

#nav li li { 
   z-index: 10;
   position: relative;
	}

And the revised css code made no difference.

The subnav displays dropdowns in front of the FCG fine using original code. No change was needed.

FCG is ver 3.0.1

This same error can also be seen on the Agent theme demo -
