Wondering what I did wrong ... or is this a bad day for the generator? I used a direct cut and paste into an existing plugin file. Attempting to view the generated options page, I get this message:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'vimeo_downloads_options_page' not found or invalid function name in ----obscured-site-name----/wp-includes/plugin.php on line 496
