Upload Form Not Saving File on Server

I hope I’m posting this in the correct place and that I can get some help here.

I have a form to upload an mp3 to the server. I works great on my dev site using MAMP, but when I test it live on my site, the file doesn’t save. I don’t get any errors, my success message even displays, but there is nothing saved. Like I said, every thing works great on my test site and the live site acts like everything worked, but there is no file saved. I first posted the page back in May and it worked then, but I have gone back to refine it a bit when I discovered this problem. Any ideas? Could it have something to do with my server config in cpanel?

I probably should add that I am getting no errors when I use the debugging tools.
