Get multiple values from popup menu and use it in different function

Hi, In the GUI I'm working, it has a pop-up menu with more than 20 options, for example person1, person2, person3.... The user can select more than one option. To allow the user to select multiple options, I defined max and min properties as 2 and 0. But, I would like to know how to get the values of multiple selections from pop-up menu to use them in a different function. Here is my code for your reference.

function popupmenu1_Callback(hObject, eventdata, handles)
   str = get(handles.popupmenu,'string');
   val = get(handles.popupmenu,'value');

switch str{val};

       case 'person1'

          name = x;
          age = 26;

       case 'person2'

           name = y;
           age = 24;

       case 'person3'

           name = z;
           age = 23;

end

Here, in the variable 'str', i get only the string of first selection in popupmenu. I want to know how to get how many options the user has selected and how to get the values of multiple selections.

If multiple values are selected, value is a vector and not a scalar. Therefore you can use:

str = get(handles.popupmenu,'string');
val = get(handles.popupmenu,'value');

for iVal = 1:length(val)
  aVal = value(iVal)
  switch str{aVal};
     case 'person1'
        name = x;
        age = 26;

       case 'person2'

           name = y;
           age = 24;

       case 'person3'

           name = z;
           age = 23;

    end
  end

I tried to find the solution from different other questions. Still I am unable to solve. Could you please help me how to fix this issue.
