bp_member_profile_data will echo out as the example in the file shows to get a field you would do:
bp_member_profile_data( ‘field=business type’)
if I wanted to see what a particular member had for that field then I might use:
bp_get_member_profile_data() and do something like:
$member_business_type = bp_get_member_profile_data('field=business type');
if ( $member_business_type == 'dj' ) :
do stuff here;
endif;
Not sure how you might apply that to your requirements but it will get you further along; also there may well be a better approach than I have outlined.
