How do I delete an upload?

[videogamer555]

I clicked the submit button multiple times when submitting a character. It didn't work the first time I clicked it, it seemed, so I clicked the button a bunch of times. The result is 3 entries for the same submission. How do I delete 2 of these? I only need one upload.
