$mallow = mysql_query($putin) or die(mysql_error());
$cap = mysql_fetch_array($mallow) or die (mysql_error());

Use LIMIT to send back a single row. Otherwise you waste a lot of time.

[code]// Retrieve all the data from the table
$result = mysql_query("SELECT * FROM teams ORDER BY RAND() LIMIT 1")
or die(mysql_error());

// store the record of the table into $row
$row = mysql_fetch_array( $result );

echo "$row[team]";[/code]
