Using CFFTP, getting Error 553

I want a user to be able to browse to a file on their local machine then FTP it to a remote server.I've been using CFFTP. I can make the connection to the server just fine. I have the path correct. I keep getting an Error 553, can't create the file. My web administrator says that he has the permissions set correctly. I don't know what else to do. I've been trying to make this work for over a month. Can someone give me a hand with this? I've tried 3 times to attach the cfm file which is 2k, but it says "content type of this attachement is not allowed." I'm pasting the code below. thanks.

<!--- Create HTML form to upload a file --->
<cfform action="test_cfftp.cfm" enctype="multipart/form-data"method="post">
