choice=menu('Choose Activity','Cooking','Cutting food');

if choice==1

choice=menu('Choose Action','Using fire to cook or boil water','w');

if choice==1

choice=menu('Choose Hazard','minor burn','major burn');

if choice==1

disp('Risk= 3')

disp('Recommended control measures=As quickly as possible soak the burn in cool water.')

else

choice==2

disp('Risk= 12')

disp('Reduce water temperature. Set the thermostat on your water heater to below 120 F (48.9 C).')

end

else choice==2

disp('Risk= 3')

disp('Recommended.')

end

else choice == 2

disp('Risk= 3')

end

A note for you, Line 2 has a spell error "choise" instead of "choice".

Hi,

For better clearity you can rename variables at each level of nesting as each of the conditional variable is names as "choice".

However the following piece of code is working fine.

choice=menu('Choose Area','Kitchen','Bathroom');
if choice==1
    choice=menu('Choose Activity','Cooking','Cutting food');
    if choice==1
        choice=menu('Choose Action','Using fire to cook or boil water','w');
        if choice==1
            choice=menu('Choose Hazard','minor burn','major burn');
            if choice==1
                disp('Risk= 3')
                disp('Recommended control measures=As quickly as possible soak the burn in cool water.');
            else
                choice==2
                disp('Risk= 12')
                disp('Reduce water temperature. Set the thermostat on your water heater to below 120 F (48.9 C).');
            end
        else choice==2
            disp('Risk= 3');
            disp('Recommended.');
            
        end
    else choice == 2
        disp('Risk= 3');
        disp('Recommended.');
    end
else choice == 2
    disp('Risk= ' );
    
end
