Hello everyone!

I am trying to make some fields to be filled as user registers to my site.

My goal is to make this condition:
if [gender=male] then [interested_in=female]
if [gender=female] then [intersted_in=male]

i have written a code for that and applied it on my functions.php file and add_action to user_registration. but no luck so far.
this is my code:

function changeinterest( $user_id ) {
			$args = array(
		    'field'     => 'My_Gender',
		    'user_id'   => $user_id
		);
		$field_name = 'My_Interests';
		$original = bp_profile_field_data($args);
		$value = maybe_serialize('male');
		$femalevalue = maybe_serialize('female');
		
if ($original = 'female') { xprofile_set_field_data( $field_name, $user_id, $value);}
elseif( $original = 'male' ){xprofile_set_field_data( $field_name, $user_id, $femalevalue);};
}
add_action( 'user_register', 'changeinterest', 10, 1 );

To me it seems correct and written ok, but I cannot understand why it’s not working.
any help would be much much much appreciated !!
