Small issue with some selection

Two popup's and one edit text box

First popup

function popupmenu1_Callback(hObject, eventdata, handles)

AUDI = {'Jhon', 'Maria'};

SKODA = {'Jhon', 'Maria', 'Nick'};

MERCEDES = {'Nick'};

% Get car model

selectedCar = handles.popupmenu1.Value;

% Fill owners popup with corresponding list of owners for that model of car.

switch selectedCar

case 1

owners = AUDI;

case 2

owners = SKODA;

case 3

owners = MERCEDES;

end

% Fill owners popup with Audi owners.

str = [];

for k = 1 : length(owners)

str = fprintf('%s\n%s', str, owners{k});

end

handles.edit1.Max = 2; % I think you need this for it to allow a multi-line edit text box.

handles.edit1.String = owners;

Second popup

function popupmenu2_Callback(hObject, eventdata, handles)

AUDI = {'Jhon', 'Maria'};

SKODA = {'Jhon', 'Maria', 'Nick'};

MERCEDES = {'Nick'};

% Get car model

selectedCar = handles.popupmenu2.Value;

% Fill owners popup with corresponding list of owners for that model of car.

switch selectedCar

case 1

owners = AUDI;

case 2

owners = SKODA;

case 3

owners = MERCEDES;

end

% Fill owners popup with Audi owners.

str = [];

for k = 1 : length(owners)

str = fprintf('%s\n%s', str, owners{k});

end

handles.edit1.Max = 2; % I think you need this for it to allow a multi-line edit text box.

handles.edit1.String = owners;

I have a new question for this code

What if ,when I select AUDI and MERCEDES, I want it to show me only if the owners who own both types of cars, if not, to show me message: "no owners who own both types of cars" ? In this case the message will be: no owners who own both types of cars

When I select AUDI and SKODA, I want it to show me only if the owners who own both types of cars , in this case Jhon and Maria.

Thank you!
