May I know what is the problem?

Currently, I'm testing a program. I wanna to delete record from the existing records.But, it always show me the warnings below.
I'm frustrated cos I cant solve the problem though I have tried so many times.

Warning shown:
Cannot modify header information - headers already sent by (output started at c:\apache\htdocs\siewpik\project\schooledit\delete Records.php:1) in c:\apache\htdocs\siewpik\project\schooledit\delete Records.php on line 53


So, may I get an idea from u guyz?
Kindly reply my thread as soon as possible, thanks a lot.

I think you're problem lies although I not exactly a pro at PHP lies in the fact your using headers and either has html before or your echo or printing out before using the headers function. To use headers you need need to place them at the top of script before any thing has been sent out to the browser.

Hope this helps.

and make sure, that the same page (incl the inclusions) dont sent more than one haeader at any time.
