Adding Users to Specific Site

I am trying to add users to specific blogs utilizing Batch Create.

The .xls file I place the blog name (i am using subdirectories) that I would like to add the user to and type in the blog name etc. The user is added but not to the site specified.

The log file is attached.

I looked in the forums and it was indicated that this plugin is not set up to be used to add users – however in the example .xls file included with the plugin it says under Site Name

“The site URL you want created or user added to (if site already exists). ex. or (No spaces, no full stops, no & allowed. Use ‘null’ without the quotation marks if you don’t want user to have a site)”

So wondering if I am missing something here orrrrr.

Any help greatly appreciated.
