WoW-Glider Keybindings

[Chrest]

Erm. Having some problem with keybindings, I downloaded Piggy's mapping (thanks a lot!) But I can't seem to get the rest bar working, whenever I try to bind a key to the rest bar, the ones from the combat bar unbind :/ Please, anyone, help me!

Anyone, please help me, I can't glide for real until this is fixed :/.
