For the pal park to work, a GBA game must be inserted along with the DS game. On the load screen there should be an option to transfer pokémon from GBA to DS. Choose tha option and transfer 6 pokemon from the pc's, not the party. then you must go to the pal park to cath those 6 pokémon. To transfer more pokémon you must wait another 24 hours. Hope this helps. ;D
