Change the value into table in GUI

I have this GUI , where I enter the values, plot the fibers and save the results in a file,

The program does successfully, but when I try to change any value in the table and press the (Plot the Fibers) button, the GUI does not work and this message appears to me

(Error using handle.handle/get

Invalid or deleted object.

Error in illcol_setup>plotthefibers_Callback (line 121)

beam_radius=str2num(get(handles.beamradius,'string'));

Error in gui_mainfcn (line 95)

feval(varargin{:});

Error in illcol_setup (line 17)

Error in

matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)illcol_setup('plotthefibers_Callback',hObject,eventdata,guidata(hObject))

Error while evaluating UIControl Callback.

)

How can I solve the problem?

the code is:

function varargout = illcol_setup(varargin)

% ILLCOL_SETUP MATLAB code for illcol_setup.fig

gui_Singleton = 1;

gui_State = struct('gui_Name', mfilename, ...

'gui_Singleton', gui_Singleton, ...

'gui_OpeningFcn', @illcol_setup_OpeningFcn, ...

'gui_OutputFcn', @illcol_setup_OutputFcn, ...

'gui_LayoutFcn', [] , ...

'gui_Callback', []);

if nargin && ischar(varargin{1})

gui_State.gui_Callback = str2func(varargin{1});

end

if nargout

[varargout{1:nargout}] = gui_mainfcn(gui_State, varargin{:});

else

gui_mainfcn(gui_State, varargin{:});

end

handles.beamradius is an Edit box in your GUI, but in the function plotthefibers_Callback, you have this line toward the end:

handles.beamradius=beam_radius;

which overwrites the value previously stored as handles.beamradius. That is, after plotthefibers_Callback executes once, then handles.beamradius no longer refers to the Edit box and instead refers to a number. So the next time when you do get(handles.beamradius,'string') you get that error because handles.beamradius is a number not a uicontrol. So maybe change that line to something like:

handles.beam_radius=beam_radius;

so that handles.beamradius is still the Edit box and handles.beam_radius is the number.
