$MySQLRecordSet = mysql_query("SELECT * FROM database_name");

What is that part used for? You seem to be doing a select query on a database, instead of a table... ?

A more common approach for fetching data would be this:

while ($row = mysql_fetch_assoc($res)) {
....
}

There seems no need to make a loop count over them when something like this is cleaner and clearer...

What is < / BR > ?

Just a few pennies worth
