Buddypress iframe on users profile with profile data

Hi everybody!
I've a buddypress website and I've a set an iFrame on the member profile page.

in the iFrame I'd like to show some of the profile fields of the user profile page.

The iFrame works properly
(js/jquery.colorbox-min.js)

I created a new file php with the call to show the fields and uploaded it in /member/single.

this is the code I have to display the iFrame:
see other fields

What should I put in the href of the iFrame to show a blank page with the profile filed of that user????

Cheers
