Forgive me for yet another question but...
What must you type into the little box (below)

I typed in "Flourite Plains" (as you can see) and, although it didn't tell me anything was wrong at the time) I found that when I tried to jump through it, it came up with this message

So what's the problem and what must I do (plz, if you can, include screenshots, cos I'm an idiot
