- The variables Total, Individual, and defaultval are not defined in the current workspace, which is the workspace of the subfunction checkbox1_Callback.
- Saving to an M-file is a bad idea, because the resulting file will not have a proper Matlab-Syntax. Use save to write binary files.
- You do not want to write the variable whose name is store in the variable Total, but the variable called 'Total'. Then you need the name as a string:

Hi, I've made a checkbox with the code below, the problem is that the variables Total, Individual, defaultval aren't saved in the workspace. How do I solve this?
function varargout = Ceckbox(varargin)
% CECKBOX MATLAB code for Ceckbox.fig
% CECKBOX, by itself, creates a new CECKBOX or raises the existing
% singleton*.
%
% H = CECKBOX returns the handle to a new CECKBOX or the handle to
% the existing singleton*.
%
% CECKBOX('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in CECKBOX.M with the given input arguments.
%
% CECKBOX('Property','Value',...) creates a new CECKBOX or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before Ceckbox_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to Ceckbox_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".

Each function has its own workspace, because this is (one of) the intention(s) of a function. Therefore this line must fail:
save('Variables.m', Total, Individual, defaultval)
It tries to save the variables, whose names are stores as Strings to the variables Total, Individual, and defaultval to the file 'Variables.m'. This contains several problems:
save('Variables.mat', 'Total')
There are more problems in the posted code: The callbacks of the buttons do not store the values permanently, but only in their current workspace, which vanishes as soon as the function is left. I do not think that close is useful in the buttons callbacks, because it prevents any further activities with the selected values.
Please explain what you want to happen with the variables. "Save in the workspace" requires too much guessing for an answer.
