Deck builder

How do you save a deck in deck builder?

Once logged in, simply press the "Submit Deck" button that is under the deck building area. 

Hi, Thanks for building an amazing page,  so cool to see all the cards here indexed and sortable.  I first tried to build a deck while not logged in,  oops!  then after creating an account, and logging in, created this same deck about four times now (maybe five) and it doesn't seem to save.  Boxes go black, and I can no longer click on them after completing some notes and then clicking submit.
could you walk us through the process of using the deck builder, say from the moment you've logged in, clicked deck builder, got sixty cards chosen and hit submit deck,  then what?
Thanks,   the two deck names I've tried to save as are All-I-Have   and zelda mipha and urbosa
