Unknown column 'var_value?' in 'field list' O_o

[n37]

CODE:

$NombreEmpresa = $_POST['NombreEmpresa'];
$ActividadEmpresa = $_POST['ActividadEmpresa'];
$Direccion = $_POST['Direccion'];
$Localidad = $_POST['Localidad'];
$Provincia = $_POST['Provincia'];
$Cp = $_POST['Cp'];
$Telf1 = $_POST['Telf1'];
$Telf2 = $_POST['Telf2'];
$Fax = $_POST['Fax'];
$TelfMovil = $_POST['TelfMovil'];
$Url = $_POST['Url'];
$Contacto = $_POST['Contacto'];
$Cargo = $_POST['Cargo'];
$Mail = $_POST['Mail'];

// Primero insertamos la empresa
$queryemp = "INSERT INTO DirectoriosNauticos
(NombreEmpresa,
ActividadEmpresa, Direccion, Cp, Localidad, Provincia, Telf1, Telf2,
Fax, Contacto, Cargo, TelfMovil, Mail, Url) VALUES ('$NombreEmpresa',
$ActividadEmpresa, '$Direccion', $Cp, $Localidad, $Provincia, $Telf1,
$Telf2, $Fax, '$Contacto', '$Cargo', $TelfMovil, '$Mail', '$Url')";
$resultemp = mysql_query($queryemp, $conex) or
die(mysql_error());

THE PAGE RETURNS:

Unknown column 'Barcelona' in 'field list'

MY EXPLANATION:

If i comment this 2 vars (like in bottom code), the error changes:

$queryemp = "INSERT INTO DirectoriosNauticos (Localidad, Provincia)
VALUES ('$Localidad', '$Provincia')";

It said:

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
'DataCenter' at line 1

Where 'Datacenter' is part of the field $_POST['NombreEmpresa']; and
default val is 'LOL DataCenter'...

I'm being crazy or there's a hidden bug? :/

All help is much appreciated. Many thx all.
