Attachments in Form do not work

I have setup the below Contact form which includes music file attachments. However, when I receive my test emails none of the files are ever attached. I have set the appropriate size and when I test they are far less. I have confirmed that I have the uploads folder and its current permissions are Owner: Read ,Write ,Execute. Group: Read, Execute, Public: Read, Execute
