Problems With GUI Running the Program

I am trying to create a GUI program that will calculate a loan payment with interest as well as duration in mounths and I keep getting the following errors well trying to run the program.

Below is the code:

function varargout = project_GUI2(varargin)

% PROJECT_GUI2 MATLAB code for project_GUI2.fig

% PROJECT_GUI2, by itself, creates a new PROJECT_GUI2 or raises the existing

% singleton*.

%

% H = PROJECT_GUI2 returns the handle to a new PROJECT_GUI2 or the handle to

% the existing singleton*.

%

% PROJECT_GUI2('CALLBACK',hObject,eventData,handles,...) calls the local

% function named CALLBACK in PROJECT_GUI2.M with the given input arguments.

%

% PROJECT_GUI2('Property','Value',...) creates a new PROJECT_GUI2 or raises the

% existing singleton*. Starting from the left, property value pairs are

% applied to the GUI before project_GUI2_OpeningFcn gets called. An

% unrecognized property name or invalid value makes property application

% stop. All inputs are passed to project_GUI2_OpeningFcn via varargin.

%

% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one

% instance to run (singleton)".

It's best if you attach the .fig file and the .m file so we can try to run it and open it up in GUIDE, for example to check if the control has a tag of "toatal_paid" or "total_paid". Why would you have a control called "toatal_paid"?
