Cases duplicated on menu Matlab

%I´m building this program, and i repeat 'case 2' but it´s for 2 different
%menus I tried to change for a text name the cases to not repeat the '2', but I think that menu
%recognize just numbers... so I don´t know what I could do... appears a
%message error saying that the cases are duplicated

%the first case 2 it´s for b1 menu
% the other one it´s for a1 menu

%Thank u!


a1=menu({'This program allows the fitting of functions to experimental points.', ...
     'To start the program, click on the Start button.'},'Start','Exit');

while a1<=2
switch a1
     case 1
         b1= menu('How do you intend to insert the experimental points?', ...
             'By a file','Manually','Back','Exit');
         switch b1
             case 2
prompt2= {'How many experimental values do you want to input?'};
title = 'Number of experimental values';
numlines=1;
ret = {' '};
answer = inputdlg(prompt2,title,numlines,ret);

             case 3
                 a1=menu({'This program allows the fitting of functions to experimental points.', ...
     'To start the program, click on the Start button.'},'Start','Exit');
             case 4
                 break

             case 2
                  break
         end
end
end

You need an "end" after "case 4, break" and before "case 2, break", to close out the "switch b1" block. And then you will need to delete one of the "end"s at the end.

switch a1
    case 1
        b1 = menu() % ...
        switch b1
            case 2
                % ...
            case 3
                % ...
            case 4
                % ...
        end % <- was missing
    case 2
        % ...
end
