Hello,
I have been trying to fix those error for quite some time now, but still haven't found the solution for them.
Code:
function varargout = ABS_gui(varargin)
% ABS_GUI MATLAB code for ABS_gui.fig
% ABS_GUI, by itself, creates a new ABS_GUI or raises the existing
% singleton*.
%
% H = ABS_GUI returns the handle to a new ABS_GUI or the handle to
% the existing singleton*.
%
% ABS_GUI('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in ABS_GUI.M with the given input arguments.
%
% ABS_GUI('Property','Value',...) creates a new ABS_GUI or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before ABS_gui_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to ABS_gui_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
%
% See also: GUIDE, GUIDATA, GUIHANDLES

Error in gui_mainfcn (line 95)

Error in ABS_gui (line 42)
gui_mainfcn(gui_State, varargin{:});
Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)ABS_gui('pushbuttonLoadXLS_Callback',hObject,eventdata,guidata(hObject))
Error while evaluating UIControl Callback.
Thanks in advance. Regards.

Attach the associated .fig file and anything else required to troubleshoot the figure setup.

GUIDE is infamous form auto-generating a lot of bloat. Let's first remove all that (and the init function, since that is the same for all GUIDE GUIs):
% --- Executes just before ABS_gui is made visible.
function ABS_gui_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject handle to figure
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% varargin command line arguments to ABS_gui (see VARARGIN)
% Choose default command line output for ABS_gui
handles.output = hObject;
% Update handles structure
guidata(hObject, handles);
function varargout = ABS_gui_OutputFcn(hObject, eventdata, handles)
% Get default command line output from handles structure
varargout{1} = handles.output;
function pushbuttonExit_Callback(hObject, eventdata, handles)
% delete(handles.figuremain)
labelStr = '<html><center><a href="">Undocumented<br>Matlab.com';
cbStr = 'web(''http://Undocumentedmatlab.com'');';
hButton = uicontrol('string',labelStr,'pos',[20,20,100,35],'callback',cbStr);
jButton = findjobj(hButton); % get FindJObj from the File Exchange
jButton.setCursor(java.awt.Cursor(java.awt.Cursor.HAND_CURSOR));
jButton.setContentAreaFilled(0); % or: jButton.setBorder([]);
function pushbuttonLoadXLS_Callback(hObject, eventdata, handles)
clc;
handles.fileName = uigetfile('*.xls');
guidata(hObject,handles);
fileName = handles.fileName;
clear a cD PiD cF PiF Jw Js D ;
%Data Input

%load experimental data from excel spreadsheet
cD; %mM
cF; %mM
Jw; %L/m2h

D = str2double(get(handles.editDiffusivity,'String')); %m2/s

IVs(1) = str2double(get(handles.editAo,'String')); %Lmh/bar
IVs(2) = str2double(get(handles.editBo,'String')); %Lmh
IVs(3) = str2double(get(handles.editSo,'String')); %micron

hButton = uicontrol('string',labelStr,'pos',[301,16,248,51],'callback',cbStr);
The source of this error means that the handle to your edit field is not correctly stored in the handles struct. You should double-check the name.
A much better idea however would be to abandon GUIDE and write the GUI yourself and only use GUIDE as a sketch pad. You are already most of the way there. For general advice and examples for how to create a GUI (and avoid using GUIDE), have look at this thread.

What changes did you make? Did you already switch away from GUIDE?
What did you try to zero in on the cause? Did you set breakpoints to inspect the values of your variables and execute the code line by line?
