Problems with CSS Footer Div

Question

Problems with CSS
I am building a new page for my company. I am trying to place the Div Footer at the bottom of the screen. I have placed (i believe) the appropriate information for the CSS.
The problem is when i minimize the browser the Footer section never leaves the screen and hovers over the other div tags. When I shrink the browser to its maximum the divs fall on top of each other.
What I would like to know is how to make the Footer div below hide like the other divs but remain at the bottom of the page instead of hovering over the other divs. I have read that I should not apply fixed divs.... is that correct?
I have applied to the current CSS to the below web page: http://trbla.com/sample.html
#rhythm {
width: 607px;
margin-top: 300px;
margin-right: auto;
margin-left: auto;
*img {
border: 0;
#rhythm #goldr {
width: 215px;
float: left;
border: 0;
#rhythm #trbnew {
float: left;
width: 181px;
border: 0;
#rhythm #greyr {
width: 211px;
float: left;
border: 0;
#nav {
margin-top: 200px;
width: 607px;
margin-right: auto;
margin-left: auto;
padding-bottom: 100px;
clear: both;
#nav #navonewrap {
float: left;
clear: both;
#nav #navwraptwo {
float: left;
width: 175px;
height: 22px;
#nav #navwrapthree {
float: right;
width: 215px;
margin-right: -75px;
#footer {
bottom: 0px;
clear: both;
position: fixed;
width: 100%;
#footer #left_footer {
float: left;
clear: left;
overflow: hidden;
#footer #r_footer {
float: right;
Thanks for anyones help thus far,

I think it's the way I'm doing the conditional statement.
'Went through another knowledge-base article that basically had me
incorporate the conditional attribute into the <xsl:for-each
select= . . .> statement and it appears to be a better way. I
also created a xslt fragment and inserted it into a php page rather
than making the whole thing xslt. I think this helps as well, but
can't absolutely close the book on this until the server is
properly configured to transform xslt in php pages.
Here's the latest
