How to repeat a prompt until a expected number is written by the user

Hi,

I would like to repeat a prompt to ask if the user wants to Stand=1, Sit=2, Sleep=3, Listen to Music=4. So, an integer number from 1 to 4 is expected from the user. If the answer (variable answer1) is not one of those values, the prompt must repeat until so. Right now, I have the following code:

while (answer1~=1 && answer1~=2  && answer1~=3 && answer1~=4)
    answer1=input('\n what would you like to do? Stand=1, Sit=2, Sleep=3, Listen to Music=4 \n')
end

However, it is not working for me. Any suggestions on this?

I thank you in advance,

Best regards,

Hugo

A = 0;
while ~ismember(A,1:4)
    A = input(..);
end

It works, thank you so much.
