Multiplayer Game Help

[charlieface88]

I searched but couldn't find anyone having difficulty with this, so I'm probably just being thick.
Anyway, I'm having trouble starting up the ad-hoc, I start one psp as the host and then hit option 2 on the multiplayer menu, it does something with ad-hoc, brings up a dialogue box with one option in it, which does nothing, just makes the PS:P error noise I'm growing to hate...Does anyone know what I'm doing wrong here?

Thanks for any help!

EDIT: I figured it out, I was going past the screen people can join at and jumping straight into the game! Silly me!
