Hi Robertu,

mysql_connect returns a value.
Check at www.php.net for details.

In this case FALSE is returned if the mysql_connect fails.
So you'll end up with something like this:
$connection = @mysql_connect("12.34.5.67.89", "Sql111111","hELLOWORLD");
if ($connection === FALSE){
echo "problem connecting...";
exit;
}

2 notes:
- The @ supresses a possible errormessage.
- the === is NOT a typo.

Also, check www.php.net for returnvalues.

This will probably not produce an error since you only construct the string.
But when you execute it you can get an error.
Also, check the returnvalue here too.

Good luck!
