Ok ;)
Teniais razon, era lo de la DB.
Lo he arreglado pero continua el problema.
Aqui el nuevo codigo:
<?php
include('localhost.php');
mysql_select_db($database_localhost, $localhost);
$result=mysql_query("SELECT hoja1.SALA, hoja1.HORA, hoja1.DIA, hoja1.ACTIVIDAD
FROM hoja1",$localhost) or die(mysql_error());
?>
<?php
echo "<table border = '1'> \n";
echo "<tr><TD> Hora</TD>
<TD> Sala</TD>
<TD> Dia </TD>
<TD> Actividad </TD></tr> \n";
do {
echo "<tr><td>".$row["Hora"]."</td><td>".$row["Sala"]."</td><td>".$row["Dia"]."</td><td>".$row["Actividad"]."</td></tr> \n";
} while ($row = mysql_fetch_array($result));
echo "</table> \n";
?>
Y aqui el localhost:
<?php
# FileName=""
# Type="MYSQL"
# HTTP="true"
$hostname_localhost = "localhost";
$database_localhost = "move";
$username_localhost = "admin";
$password_localhost = "buleta";
$localhost = mysql_connect($hostname_localhost, $username_localhost, $password_localhost) or trigger_error(mysql_error(),E_USER_ERROR);
?>
Muchisimas gracias ^^
