Facing this problem “Warning: Undefined array key “eael_pricing_table_button_show” on line 2349 but i’m unable to resolve it. kindly let me know how can I fix this?

`<?php if($settings['eael_pricing_table_button_show']=='yes'): ?>
                <div class="footer">
                    <a <?php echo $this->get_render_attribute_string('eael_pricing_button'); ?> >
                        <?php if ('left' == $icon_position) : ?>
                            <?php if (empty($settings['eael_pricing_table_button_icon']) || isset($settings['__fa4_migrated']['eael_pricing_table_button_icon_new'])) {
                                Icons_Manager::render_icon( $settings['eael_pricing_table_button_icon_new'], [ 'class' => 'fa-icon-left'] );
                            } else { ?>
                                <i class="<?php echo esc_attr($settings['eael_pricing_table_button_icon']); ?> fa-icon-left"></i>
                            <?php } ?>
                            <?php echo $settings['eael_pricing_table_btn']; ?>
                        <?php elseif ('right' == $icon_position) : ?>
                            <?php echo $settings['eael_pricing_table_btn']; ?>
                            <?php if (empty($settings['eael_pricing_table_button_icon']) || isset($settings['__fa4_migrated']['eael_pricing_table_button_icon_new'])) {
                                Icons_Manager::render_icon( $settings['eael_pricing_table_button_icon_new'], [ 'class' => 'fa-icon-right'] );
                            } else { ?>
                                <i class="<?php echo esc_attr($settings['eael_pricing_table_button_icon']); ?> fa-icon-right"></i>
                            <?php } ?>
                        <?php endif; ?>
                    </a>
                </div>t`
