It's a collision with another snippet, or you have two fileUpload() tags on the same page. If it's the latter, the fix is easy, but I should really refactor fileUpload to put that function in a class. Let me know which it is.
Also, what snippet has the ID of 60? Is it the FileUpload snippet or something else (and if so what snippet is it)?
I don't think that would be related to the upload limit or the upload location, but it's possible. Let me fix it and you can see.
