what is the wrong with my code?

z=6;
if z==6
    prompt = "what type of threaded pipe fitting  (Globe (1)/Angle (2)/GateWide (3)/Gatehalf (4)/Return (5)/Tee (6)/Straight-Through (7)/Side-outlet (8)/90 (9)/45 (10)): ";
    y=input(prompt,"s");
    
    if y=='1'
        k=10;
    else
        if y=='2'
            k=5;
        else
            if y=='3'
                k=0.2;
            else
                if y=='4'
                    k=5.6;
                else
                    if y=='5'
                        k=2.2;
                    else
                        if y=='6'
                            k=0.4;
                        else
                            if y=='7'
                                k=1.8;
                            else
                                if y=='8'
                                    k=0.9;
                                else
                                    if y=='9'

                                        y="Error";
                                    end
                                end
                            end
                        end
                    end
                end
            end

Hi,

check this

z = 6;
if z == 6
    % Assign the desired value of y based on your requirements
    y = '6';  % Example: Assigning '6' for Tee fitting

    switch y
        case '1'
            k = 10;
        case '2'
            k = 5;
        case '3'
            k = 0.2;
        case '4'
            k = 5.6;
        case '5'
            k = 2.2;
        case '6'
            k = 0.4;
        case '7'
            k = 1.8;
        case '8'
            k = 0.9;
        case '9'
            k = 0.4;
        case '10'
            k = 0.45;
        otherwise
            disp("Invalid option.");
            % Handle the error condition based on your program's logic.
    end
end
