The crossfire gm contest video

I don't know if I'm doing it right... I went to the contest page and then to "SUBMIT AN ENTRY" and even if I pasted in the link and the title, it doesn't do anything, just the page refreshes, am I supposed to get some kind of message saying that it has been submitted?

I clicked it multiple times, relogged and I never get a confirmation.. just tell me please if I did it right, I really want to participate but I don't know if I even submitted the video right.
