How to clear the contents of an app designer text area?

Below is my code:
% --- create a file to store the QC comments ---
File1 = ['comments/QCcomments_' app.FileName.Value '.txt'];
fid = fopen(File1, 'at'); % append
fprintf(fid, '%s\n', ['Station No: ' num2str(app.StationNo.Value)]);
fprintf(fid, '%s\n', char(app.QCcomments.Value));
fprintf(fid, '%s\n', '');
fclose(fid);
What I want to do is to clear the app.QCcomments contents. I tried to use:
app.QCcomments.Value = ''
and it did not work.
Many thanks in advance!

So,
app.QCcomments.Value = '';
should clear the text area. Is there any error message?
