2nd ciphers on Besaid (something different!)

just wanted to say that i’m at the bit where you find the second set of ciphers on besaid island, and i’ve found all the ciphers (i can’t read half of them, but that’s a different story) but i don’t know what to do now. i’ve tried going up to the key pad at the entrance to the cave and hitting X, like with the first set but nothing happens. I’ve also searched inside the cave, and can’t find where I’m supposed to key in the cipher numbers. is there something else i’m supposed to do first?

Cheers 😉
