Oh God, I see what I've been doing. I was putting the seed in the place that was actually marked "PID". *faceslap* Thank you for your help. I might come back with more questions later.
EDIT: So, do I find a nonshiny PID, say 31/31/31/31/31/31, that I want to "turn shiny," and then perform the steps you listed for it starting with that PID?
