How to Create Dynamic Sidebar in WordPress?

I am working with a theme that has a header ad widget (which displays an ad block at the top of each page). But, I want the homepage to show a different ad block than the rest of the site. I am teaching myself so any help from a PRO is appreciated.

So far, I have:

The ad widget code in my header-main.php file is:

[CODE]<div class=”body-wrapper”>

<header id=”header”>
TESTING
<?php if ( wpb_option(‘header-widget-ads’) ): ?>
<div class=”ads-header group”>
<div class=”container”>
<div class=”grid one-full”>
<ul><?php dynamic_sidebar(‘widget-ads-header’); ?></ul>
</div>
</div>
</div><!–/.ads-header–>
<?php endif; ?>

[/CODE]

I have reviewed my functions.php file but I am not sure what code to duplicate?

[CODE]
<?php

/**

Many tutorials suggest placing code in the functions.php file. This file
is used to configure the theme’s framework. Editing may break your theme.

Please use the custom-functions.php file for customization. Thanks! 🙂
