File attachments

Hi,
I am making a mail interface which would allow the user to attach file to the sending mail.

I tried using cfmail 'MIMEAttach' parameter as well as 'cfmailParam' parameter too. Problem is that the page does not recognize the file that I select from my hard disk. It seems it would only look on the machine on which it runs.

e.g. If I choose the file "c:\a.txt" which lies on my machine and the coldfusion engine is running on another machine, then it will search for 'a.txt' on the c: of the other machine.

Any idea how do I go about attachments?

Thanks!
