how do i avoid getting error msg when writing to a file?

[visualaddiction]

HI guys

After you very nice people helped me use php to write to a file, I came across a few problems, the first one was this error msg :

"Warning: fopen("news.txt", "a") - Permission denied in /home/sites/site22/web/newsitem.php on line 3
Could not write to file"

Does this mean that on the server that this is on I cannot write to files at all? Or is there a way to bypass the permission thing.

Also one other thing which some of you might help me with. I can work out how to add text to the .txt file, but I need to add it to the beginning BUT after some other text. Because i'm using this with flash, the first thing in the file needs to be "varnews="

thanks for looking and I hope you can help.

Colin.

Well you must chmod that file 777 so you can write to it. If its not on the server but on a Windows Machine Im clueless
