Before Record Updated Not Working

Hi,
if you use PHPRunner 5.1 use this code:

if ($values["Field1"] ==1 && $values["Field2"] == 1)

{

ob_end_flush();

echo "<center><b><font color=red>¡Field1 & Field2 Checked!</font></b></center>";

return false;

}

else

{

return true;

}

or this one:

if ($values["Field1"] ==1 && $values["Field2"] == 1)

{

$message = "<center><b><font color=red>¡Field1 & Field2 Checked!</font></b></center>";

return false;

}

else

{

return true;

}
