Widgitzed Sidebars

I’m using some if thens to make my sidebars different for each page.. Problem I run into is that the home page doesn’t want anything to do with it.

Here’s part of the sidebar statement:

if(is_home() || is_front_page()) {
if (!function_exists('dynamic_sidebar') || !dynamic_sidebar( 'home') ) { $generic_sidebar = true; }
}
elseif ( is_tree('about') ) {
if (!function_exists('dynamic_sidebar') || !dynamic_sidebar( 'about') ) { $generic_sidebar = true; }
}
...etc

And the functions:

if ( function_exists('register_sidebars') ) {
register_sidebar(array('name'=>'home'));
register_sidebar(array('name'=>'about'));

So I’m not sure really how to use the if_home and the is_tree together..

The sidebars on the pages work, but the home page refuses to work. Can anyone help??
