slight coding help (CSS)

[Apui]

I have a set color for links on my site.

a { color: #FF9900; }

however, I want the links to appear white in my "nav" div. I do the following

a#nav { color: #FFF; }

However this doesn't seem to work, does anyone know what I'm doing wrong? I have a feeling it's the a#nav part.

Please if you know could you help me, and if you don't know, please don't post... I don't want to read through stuff that isn't the answer to what I need.

Thanks in advance

#nav a {color: #fff;}

Wow, I feel like an idiot

I tried like
a#nav
#nav.a
#nav:a
a:#nav

all of thos types of things and it's just that.

Cheers
