error in gray area of app designer

My app suddenly is giving an error (see below) in the gray code. I can not change the gray ares so how do I fix it?

Thank you Paul Mulqueen

methods is underlined in red. The erroe is Line 178 Parse error at methods usage might be invalid in MATLAB syntax.

% Callbacks that handle component events

methods (Access = private)

% Cell edit callback: UITable

function UITableCellEdit(app, event)

end

Hello,

You can't change grey area, check if you're missing an end somewhere in your code.

I have never seen variable in yellow. Usually, " ! " commands are marked in yellowish color.

I needed to comment out a function to fix it. The end statements were fine. I gave up on app designer and quickly built what I needed in Excel. I just use MatLab for the math part.
