Could we try to keep personal insults out of this please? Thanks. As you may have noticed, I had answered the question alredy in an earlier reply.
Other than that, I simply pointed out that file uploads in CGI may seem confusing and unintuitive to the beginner and therefore I think it is ok to ask here. The OP had also included code in the question, so for that reason I pointed out that, in my view, the "How to ask a question" link was not quite appropriate. Please note that I didn't shout you down or insult you, but simply voiced my opinion. There is really no reason to insult me.
