Thats worked great...Thanks!
I'm now trying to remove the model from the cart page as well, I've managed to find where the code is in the /public_html/storefront/view/default/template/pages/checkout/cart.tpl but if I remove the lines which I've found which contain the word 'model'
Line 32 <th class="align_left"><?php echo $column_model; ?></th>
and
Line 54 <td class="align_left"><?php echo $product['model']; ?></td>
it does actually remove the model number but still leaved the heading 'title' and the price is now listed under the model
Any ideas again much appreciated.
