Body
Firstly, we see in the error message that there was a <code>boolean given</code> - the only reason <a href="http://php.net/manual/en/function.mysql-query.php" rel="nofollow"><code>mysql_query()</code></a> returns a boolean for a SELECT query is if the query failed - which it will have done because you have a syntax error in your SQL. You need to change some of the single quotes to backticks: <pre><code>$query = " SELECT `ip_count` FROM `count_ip` WHERE `ip_count` = '$ip_add' "; </code></pre> Object names (columns, tables etc) should be quoted with backticks `, anything surround with single quotes ' is treated as a literal string. You need to check for the failure of the query: <pre><code>$query_run = mysql_query($query); if (!$query_run) { // Handle error here } $query_num_rows = mysql_num_rows($query_run); </code></pre> Some additional comments: <ul> <li>Try and indent your code more sensibly, it will make it much easier to debug in the long run</li> <li>Avoid the use of global variables, they are very bad practice, especially when you are populating them with data that is already <a href="http://php.net/manual/en/language.variables.superglobals.php" rel="nofollow">superglobal</a></li> <li><a href="http://bobby-tables.com/" rel="nofollow">Make sure you escape any data from external sources before using it in a database query</a></li> <li>Don't use the <code>mysql_*</code> functions, use <a href="http://php.net/manual/en/book.pdo.php" rel="nofollow">PDO</a> or <a href="http://php.net/manual/en/book.mysqli.php" rel="nofollow">MySQLi</a></li> </ul>

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
