If statement error code mistake - string input too long not working...

Question

I essentially have this as code in the GUIDE GUI pushbutton1_Callback. Error Code II is not working properly. Even if I enter in say "Bob" in the empty textbox and push the button, its giving me Error Code II (the elseif statement). What's the issue here? Input would be greatly appreciated.

if isempty(editString)
    errordlg('Please enter a name into the text-box. ...','ErrorCode I');
    return
elseif char(editString) > 12
    errordlg('Please enter a name with less than 12 characters. ', ...
             'Error Code II');
else 
    delete(gcf)    
    gui_02
end
