Want to create a loop that gets 12 arbitrary numbers between 1-20 from the keyboard

I want to create a function or just an m-file that reads 12 arbitrary numbers, from the keyboard to a vector one at a time. The numbers should be in the range 0-20.
This is what I did so far but it doesn't work.
for i=1:12, c=input('Write 12 numers between 0-20: ','s'); %I don't necesarely want it to ask everytime but I dont know how to make it ask one time. c(i+1)=c;
%if x>=20 (to get an error message if you type in the wrong number) %p='Error'; %p %end
Hope somebody can help!

An example of code, you can make more robust introducing more checks:
c = zeros(12,1);
% Set counter
ii = 1;
while ii <= 12
% Get value
c(ii) = input('Write 12 numers between 0-20: ');
% Check if in [0-20]
ii = ii+1;
fprintf('\nWARNING: Only values between 0-20!\n')

you're using "c" as your input vector but then you're not filling it, you're redefining it
c(i)=str2num(input('Write 12 numers between 0-20: ','s'));
if c(i)>20 || c(i)<0
error('You have to specify a number between [0-20], now start over')
This should work
