if ($firstname == '' || $lastname == '')
try changing this to:
if ((!isset($firstname)) || (!isset($lastname))) {Thanks for suggestion; didn't work, though -no error, just empty page....

I've been following the video's to the letter, literally
, but still don't get the error message when not all fields in the form are filled in.Here is my code (but, if it's easier for you, send me yours and I'll be able to figure it out by myself).
Thanks,
