I can't figure out how to get this to work…

I have been trying to figure this out for a few months now and I honestly just can’t understand it. I’m really sorry for posting this here because I feel like it’s probably something really simple and i hate to waste your time. But I would DEEPLY appreciate help.

I installed the plugin, I have 5 sites total, with one being my main site (www.withalittlemoxie.com). My settings look like this:

Tags Blog Enabled
You can create your post archive in a specific ‘tags’ blog of your choosing, or you can use the main blog of your site. Each has it’s own pros and cons.

Blogname of the blog your global tags and posts will live in. Blog will be created.
Post to main blog
Create posts in your main blog. All posts will appear on the front page of your site. Remember to to add a post loop to home.php in the theme directory if it exists.
Max Posts
The maximum number of posts stored in the tags blog.
Include Pages Enabled
Include Post Thumbnails Enabled
Privacy Tags pages can be indexed by search engines.
Tags pages will not be indexed by search engines.
Will your tags pages be visible to Google and other search engines?
Non-Public Blogs Enabled
Include posts from blogs not indexed by search engines.
Post Meta
If you want to copy custom fields with posts. One custom field per line.

Populate Posts Blog ID: OR
All blogs
Add posts from the blog named above or all blogs to the sitewide tags blog. This page will reload while copying the posts and may take a long time to finish.
Note: Depending on your server resources, you may need to turn off other plugins while using the populate feature.

What am I doing wrong? What do I need to put in so that it will post all posts to my main blog?

Thank you SO MUCH in advance for any and all help – I really appreciate it.
