Sorry if it\'s a quite simple problem. I am not too experienced with web languages.
Basically, it doesn\'t work.
$insert=
(
\"INSERT INTO phpbb_members
I think the problem may be in the way you've laid out the information to be inserted.
This should work:
$insert=("INSERT INTO phpbb_members (emailAddress, uid, valid, firstandlast, propic, memberName)
VALUES ('$me[email]', '$uid', '1', '$me[name]', '$propic', '$newuser')");
mysql_query($insert) or die('Error, insert query failed');
Hope it helps!
EDIT: I'm pretty sure the information to be inserted has to be inside ' '.
