Trying to redeclare a previously declared function

Hi everyone, I'm getting this error http://prntscr.com/droash that I'm trying to redeclare a function in a file with a strange name, obviously it's my first time trying to declare this function so I'm wondering how can I proceed with this.

Thanks in advance!

plugin.php 
<?php

function my_plugin_menu() {

    // Page Title: My Plugin Settings Page
    // Menu Title: My Plugin
    // Slug: Same as menu name, but with hyphens instead of spaces
    // Make sure user has ability to manage plugin options
    // my_plugin_options_page() is the function for what displays on the options page
    add_options_page(
        'My Plugin Settings Page',
        'My Plugin',
        'manage_options',
        'my-plugin',
        'my_plugin_options_page'
    );
}
add_action( 'admin_menu', 'my_plugin_menu' );

function add_options_page() {
    if( !current_user_can( 'manage_options' ) ) {
        wp_die( 'You do not have suggicient permissions to access this page.' );
    }
    echo '<p>Welcome to my plugin settings page.</p>';
}

?>
