Wordpress and MySQl and PHP Error on attempt to Install UserOnline Plugin

try this syntax:

// Create Useronline Table
$sql[] = "CREATE TABLE {$wpdb->useronline} (".
  " `timestamp` int(15) NOT NULL default '0',".
  " `username` varchar(50) NOT NULL default '',".
  " `ip` varchar(40) NOT NULL default '',".
  " `location` varchar(255) NOT NULL default '',".
  " `url` varchar(255) NOT NULL default '',".
  " PRIMARY KEY  (`timestamp`),".
  " KEY `username` (`username`),".
  " KEY `ip` (`ip`),".
  " KEY `file` (`location`))";

now, you might want to eacho out the $sql[] value(s) to the output to see what the value is, to see if th evalue is properly filled in.

I tried the above syntax and still getting this error :

WordPress database error: [You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '( `timestamp` int(15) NOT NULL default '0', `username` varchar(]
CREATE TABLE ( `timestamp` int(15) NOT NULL default '0', `username` varchar(50) NOT NULL default '', `ip` varchar(40) NOT NULL default '', `location` varchar(255) NOT NULL default '', `url` varchar(255) NOT NULL default '', PRIMARY KEY (`timestamp`), KEY `username` (`username`), KEY `ip` (`ip`), KEY

as you see in the CREATE TABLE statement, the name of the table is not there.
which simply means that the value of $wpdb->useronline is empty.

get that fixed, and your create table statement will work better

The install code,  that runs the failing SQL has that require_once n(../wp_config.sys) in it already...
I tried anther approach.  I added a connection with  MySQL admin and created the table.

Now,  the pluggin gets enabled but does nothing.  I have followed the install instructions, but I only see the plugin in the admin to activate/deactive it.  But the plugin does not seem to do as expected.  It seems as though some environment settings are not there.  I did add the statement to the wp-settings.php file for the $wpdb->useronline variable (the wp-config.php inludes the wp-settings file which is where the variable is declared/set -- I think).

It is the usersonline plugin that I have used with little or no effort at other web blogs before.  I will send the pieces here :

It is a business blog, so I am trying to be extremely cautious with my experiments / "enhancements".

Please advise.
