Im using Amastys Gallery plugin to implement into a tab on the product page, however the above error has come up when I pasted the code into my custom template.

I have called my tab in the local.xml

<block type="catalog/product_view" name="catalog.product.gallery" template="catalog/product/view/gallery.phtml">     <action method="addToParentGroup"><group>detailed_info</group></action>     <action method="setTitle" translate="value"><value>Gallery</value></action> </block> 

And the below code is within my gallery page:

This is being pulled in fine when I use the below on the view.phtml

<?php echo $  this->getChildHtml('product_additional_data') ?> 

Any pointers would be greatly appreciated.

Thanks
