DS Pearl - evolve Pikachu with Thunderstone

[Poke Granny]

My son got a DS and Pearl for his birthday a couple weeks ago, he is trying to evolve Pikachu with the Thuderstone. He attached the thunderstone but nothing has happened.

Why not?

I am not a DS/Pearl geek but I am sure he will understand whatever you say even if I don't

You must 'use'the item from the item menu rather then letting a Pokemon hold it.

Yes, select "use item", then it will show his Pokemon. Select Pikachu, and it will evolve.
