In Chapter 12 it adds .navbar style to WroxUnited.css which adds a border round the navbar, however, when I repeat this for the WroxUnited2.css this effect is not reproduced. Can someone explain to me why this is. I reproduce my WroxUnited2.css, just in case there is something in there which is causing this not to work.

BODY {
    background-image:url(images/awaybackground.gif);
    color:#ffffff;
    font-family: georgia;
}

a {
    color:yellow;
    font-weight:bold;
}

.selecteddate{
    font-weight: bold;
    font-size: larger;
    border: 3 dotted white;
    background:#c0c0c0;
}

.normaldate{
    font-weight:lighter;
    color:#d3d3d3;
}

.calendar a{
    text-decoration:none;
    font-size: 10pt;
}

.othermonthdate{
    font-weight:lighter;
    color:dimgray;
}

.datatablebody{
    background-color:#ffffff;
    color:black;
    font-size:smaller;
}

.datatablebody td{
    padding:3;
}

.datatablehead{
    background-color:#c0c0c0;
    color:black;
    font-size:bold;
}

.datatablehead td{
    padding:3;
}

.navbar{
    width:185px;
    border-bottom-width:4;
    border-bottom-color:#c0c0c0;
    border-bottom-style:solid;
    border-right-width:2;
    border-right-color:#c0c0c0;
    border-right-style:solid;
    padding-right:1;
    padding-bottom:0;
    padding-top:0;
}

Since posting this I have run it in Firefox and after refreshing (keep getting server error in relation to DateList first time I run it after any changes), now working in IR too, since doing this, don't know what caused the problem.
