TROUBLESHOOT: are the two versions with witch you are attempting to trade compatible with each other? are the Pokemon you are attempting to trade found in the version you are attempting to trade it to? are you in the right place to trade your Pokemon? is the cable actually meant to trade information among GAMEBOY/NINTENDO DS?

If you have two DS's, or a friend with a DS, you can trade between the two games by going to any Poke Center and going into the Union Room. You can trade between the two games.
No, you have to have 2 Nintendo DS's to be able to trade but you do get an a attachment for you're DS that allows you to plug it into the DS card slot and have two DS card slot's
You can give it to a Rhydon and then trade it and it will evolve into a Rhyperior. You can trade it to yourself and then trade it back to your game or, if you don't have two Nintendo DS', trade it to a trustworthy friend and then trade it back to your game. DO NOT TRADE OVER GTS. You will never get it back. Probably.
You need two Nintendo DS game consoles, you go the top floor of the Pokemon centre, and then go in the link room and select trade.
You cannot trade between Pokémon Ranger and Pokémon Black 2.
