I want to show some product custom attribute in product view page at TAB like following image.
So far I've tried following
<?php $_product = $this->getProduct(); ?>
But it return with NULL
Then I tried following
<?php $_product = Mage::registry('current_product'); ?>
But after using above the page goes blank and nothing will appear.
I'm making changes in following path
In core file just for testing purpose. Once It will work I'll override it.
