Random number game repetition help

I am trying to create a number guessing game that keeps repeating until you guess the number. If I guess the number correct then I want it to ask to keep playing. If the user wants to keep playing, the code should repeat, but it is not working right now.

     clear
     clc
startChoice = input('Would you like to play this high-tech game? Enter 1 for yes and 0 for no!');
guessNumber = randi([1 50],1,1);
    while startChoice == 1   
        guess = input('What number do you pick? ')
        if guess < guessNumber
            startChoice = input('You guessed to low. Would you like to keep trying? 1 for yes, 0 for no. ')
        elseif guess > guessNumber
            startChoice = input('You guessed to high. Would you like to keep trying? 1 for yes, 0 for no. ')
        elseif guess == guessNumber
            startChoice = input('You guessed correct! Would you like to play again? 1 for yes, 0 for no. ')

            while startChoice == 1
               guessNumber = randi([1 50], 1, 1);
               guess = input('What number do you pick? ')
            end
        end
    end
    if startChoice == 0
        disp('Wowwwww, you are no fun!')
    end

Try this:

clc
playAgain = input('Would you like to play this high-tech game? Enter 1 for yes and 0 for no : ');
if playAgain ~= 1
  helpdlg('Wowwwww, you are no fun!')
  return;
end
highestNumber = 5;
computersNumber = randi([1 highestNumber],1,1);
usersGuess = input('What number do you pick? ');
while playAgain == 1 && usersGuess ~= 0
  if usersGuess < computersNumber
    usersGuess = input('You guessed too low.  Enter your next guess, or 0 to quit : ');
  elseif usersGuess > computersNumber
    usersGuess = input('You guessed too high.  Enter your next guess, or 0 to quit : ');
  elseif usersGuess == computersNumber
    playAgain = input('You guessed correct! Would you like to play again? 1 for yes, 0 for no. ');
    if playAgain == 0
      break;
    end
    % Get a new computer's choice.
    computersNumber = randi([1 highestNumber], 1, 1);
    usersGuess = input('What number do you pick? ');
  end
end
if playAgain == 0
  helpdlg('Wowwwww, you are no fun!')
end
