How do you change your player in the sims 2 castaway psp?

To change players in sims 2 castaway (PSP) you have to find at least one crew member and invite him/her into your tribe. Then you have to make sure you're in the same place, when your sims are close then click on L and then the 'right' control pad ( the one with the four arrows) then keep it like that for like five secs and use that same sontrol pad to choose out of all the simses that you can control. Sorry if it's not so clear I'm not very good at explaining stuff like this! ^.^
