How to continue an if statement after using the switch function

I imbedded a switch function into an if statement but I'm finding it hard to nest my next if statment to the previous one.If you run this code it will only work half way.

In this code use the number 332837840 (when asked to type in:)

% scd must be a 9 digit number.
scd = input('Type in: ','S');
conDIG = scd - '0';%converting to digits
scued =(conDIG(1)*conDIG(3))-conDIG(5);
if scued > 7 || scued < 1
    disp('De')
else
    switch scued
        case 1
            disp('M')
        case 2
            disp('T')
        case 3
            disp('W')
        case 4
            disp ('T')
        case 5
            disp ('F')
        case 6
            disp ('S')
        case 7
            disp ('S')
        otherwise
            disp('A')
            if scued > 7 || scued < 1
                mpt = conDIG(2)*conDIG(4)- conDIG(6);
            else
                disp('De')
                if  mod(mpt,3) ~= 0
                    rendzP = conDIG(8)- conDIG(9);
                else
                    rendzP = conDIG(7)- conDIG(9);
                    if rendzP > 7 || rendzP < 1
                        disp('De')
                    else
                        switch rendzP
                            case 1
                                disp('b')
                            case 2
                                disp('l')
                            case 3
                                disp('r')
                            case 4
                                disp('a')
                            case 5
                                disp('b')
                            case 6
                                disp('l')
                            case 7
                                disp('D')
                            otherwise
                                disp('De.')
                        end
                    end
                end
            end
    end
end

Right now, your second if statement is part of the otherwise case of the switch statement. If you want it to execute after the switch statement, you need to move the closing end to the end of the switch statement.

if ...
    code
else
    switch var
        case 1
            code
        case 2
            code
        otherwise
            code
    end % end of switch statement
end % end of first if statement
if ...       
    code
end % end of second if statement
