Whatever submission I click, I always get the same error. The subs I want to make are for the DDR1 Dogpile stage. It would be a pain for me to manually add the hardware used for every single sub (plus adding the screen and photo). I tried with two different computer, but both resulted in the same error page.

This feature does not work with competitions. Sometimes the competition pop up will appear when doing a normal sub and you can enter that way (after using the populate using a recent entry) but this doesn't seem to be the case with Team Cup this year. 

Sometimes "prepopulate fields by previous submission " works, most time not.
