How do i get user input into msgbox

So for my engineering project, I am creating a text based adventure because it sounds fun. So the first prompt players are greeted with is as follows:

playername = inputdlg('Welcome to The RPG, what is your name?:', 'RPG', 1);

charactername= playername{1};

msgbox(sprintf('Nice to meet you %g', charactername))

So the player is suppose to enter their name, and then I'd like the message box to restate their name, but when I run the code this happens "Nice to meet you98Nice to meet you 101Nice to meet you 110"

Any ideas?

I got it it, heres the code:

playername = inputdlg('Welcome to The RPG, what is your name?:', ' RPG', 1);

charactername= char(playername(1));

msgbox(sprintf('Nice to meet you %s\n', charactername))
