Hello,
I have seen this question asked before but for some reason I still can't see where the error is in my code. I am a newbie to PHP so that could very well be the problem right there. 😛 Anyway, I am getting this error:
Warning: Cannot modify header information - headers already sent by (output started at /home/careac5/public_html/login.php:18) in /home/careac5/public_html/login.php on line 78
My code is as follows, and this is exactly how it is in the file.

If anyone can help me that would be great. At the very least a point in the right direction would be a nice start. If you need anything more please let me know. Thanks in advance.
