I hadn't opened the file with FrontPage or edited it in any way. After reading your reply, I re-uploaded the file (post_info.asp) but it still refused to work. So I went back and unzipped a fresh copy. Still no luck. Then I noticed my Zipit was set by default to strip linefeeds from text files. I turned that off, unzipped and unloaded the file again, and now it's working. I'm assuming that was the problem.
