Hi,
I got an error message in my code that occurs this morning.
I use questdlg in my code which was fine yesterday, but this morning I got an error message, as shown in the image below.
Does anyone know how to overcome this issue? Because yesterday was working fine but this morning is not working !!!
Thank you

Okey
The erro in my code in this part
answer1 = questdlg('Strained Method?', ...
'Options',...
'Expanded strain at the facet','Compressed strain at the facet','');
This was fine yesterday, but today is changing, I do not know, is it MATLAB change the function or something
questdlg function debug is there
if ~DefaultValid
warnstate = warning('backtrace','off');
warning(message('MATLAB:questdlg:StringMismatch'));
warning(warnstate);
end

Add the default button (last argument) to be one of the specified buttons:
answer1 = questdlg('Strained Method?', ...
'Options',...
'Expanded strain at the facet','Compressed strain at the facet','Expanded strain at the facet');
