Custome Payment Gateway Settings not Saving

Hello! I’m running the newest version of WooCommerce. (2.1.7) I am trying to use my custom payment gateway, but the settings for it don’t seem to be saving. It gives me the message settings saved, but they stay the same. My need part of my code is as follows, (I didn’t include the slew of callback code or the unrelated shortcode for interacting with the user.)

<?php

Plugin Name: Bitcoin WooCommerce Payment Gatway
