 * Hey all…I’m trying to write a plugin that will create and fill some mysql tables
   and I’m testing it out by going through the [Creating Tables with Plugins](http://codex.wordpress.org/Creating_Tables_with_Plugins)
   tutorial. I have an install.php file that contains everything copy and pasted
   from the code under “The Whole Function” section, and have a plugin file that
   only does `add_action('activate_plugindir/pluginfile.php', 'jal_install');`
 * When I activate the plugin, I get the following error
 * > Warning: call_user_func_array(): First argumented is expected to be a valid
   > callback, ‘jal_install’ was given in /home/litscher/public_html/testblog/wp-
   > includes/plugin.php on line 123
 * This is a fresh WP 2.1.2 install with no other plugins activated and the default
   theme. Any help would be greatly appreciated. Thanks.
