condition if buddy

[kube]

Here is my problem:

There is no really good profil page, so I modificated mine and I want to use some custom profile fields only shown for buddies.

It´s no problem to show fields if you have the one which profile you are visiting on your buddy list BUT I want to show the fields only if you are on HIS buddy list.

Does anyone know how to manage this ?

I also tried it with a special field, where you write down the ID of your friends - but this also do not work....
