NextGen Flex Slider won't work

I am having difficulty getting the NextGen Flex Slider template plugin to work with the attitude theme. The short code that I am supposed to use is:

[nggallery id=x template="sliderview"]

I have tried to use the instructions found in the post earlier in this forum at here

So creating a child-header-extensions.php and a child functions.php, and using the child functions php to override the call to header-extensions.php and then using the shortcode in the child-header-extensions php with the following to implement the slider:

<?php if ( is_page( 'home' )) echo do_shortcode('[nggallery id=2 template="3dfluxsliderview"]'); ?>

But I just can’t get the slider to work. I am wondering if there is something in my attitude theme that is overriding the slider plug-in? Or am I just putting the code in the wrong place in the child-header-extensions.php. I placed it right before the get_header_image in the attitude_headerdetails function as below:

</div><!-- .container -->
    <?php if ( is_page( 'home' )) echo do_shortcode('[nggallery id=2 template="3dfluxsliderview"]'); ?>
    <?php $header_image = get_header_image();
			if( !empty( $header_image ) ) :?>
				<img src="<?php echo esc_url( $header_image ); ?>" class="header-image" width="<?php echo get_custom_header()->width; ?>" height="<?php echo get_custom_header()->height; ?>" alt="<?php echo esc_attr( get_bloginfo( 'name', 'display' ) ); ?>">
			<?php endif; ?>
	<?php

This all seems very complicated to get a simple slider to work. What am I doing wrong? Thanks.
