basic php errors ( turn on WP_DEBUG to see )

Hi,

I'm not sure why, but I've installed 4 plugins from WPMU so far, and each has basic ( non-critical ) errors - here's the list for this plugin:

settings > mailchimp ( after install, no key entered )

Notice: Undefined index: action in C:\xampp\htdocs\gh-info\wordpress\wp-content\plugins\mailchimp-sync\mailchimp-sync.php on line 174
Notice: Undefined variable: mailchimp_lists in C:\xampp\htdocs\gh-info\wordpress\wp-content\plugins\mailchimp-sync\mailchimp-sync.php on line 290

-- it briefly shows 3 extra errors when saving the key, but too quickly to see, they will need to be debugged by the developer.

-- after entering a key:

Notice: Undefined index: action in C:\xampp\htdocs\gh-info\wordpress\wp-content\plugins\mailchimp-sync\mailchimp-sync.php on line 174

Thanks

Ray
