Yes, I have made it too. I have changed ajax-cart.js file, in product.js I have still up and down. In ajax-cart.js was up & down, when I clicked on + or - button I was moving to the top of the site (and nothing else happens), but when there is incr & decr just nothing happens. Now the code is like I send before. Maybe I forget about something else? Or maybe I have to do it in different file?

Thanks for the answer. I have made minimalQuantity like you said, now it is like this: // The button to increment the product value $(document).on('click', '.product_quantity_incr', function(e){ e.preventDefault(); fieldName = $(this).data('field-qty'); var currentVal = parseInt($('input[name='+fieldName+']').val()); quantityAvailableT = 100000000; if (!isNaN(currentVal) && currentVal < quantityAvailableT) $('input[name='+fieldName+']').val(currentVal + minimalQuantity).trigger('keyup'); else $('input[name='+fieldName+']').val(quantityAvailableT); }); // The button to decrement the product value $(document).on('click', '.product_quantity_decr', function(e){ e.preventDefault(); fieldName = $(this).data('field-qty'); var currentVal = parseInt($('input[name='+fieldName+']').val()); if (!isNaN(currentVal) && currentVal > 1) $('input[name='+fieldName+']').val(currentVal - minimalQuantity).trigger('keyup'); else $('input[name='+fieldName+']').val(1); }); but it is still nothing, I can say that nothing happens when I click + or - button. I made a modification on your code in product-list.tpl to show minimal quantity in box instead of 1: <input type="number" min="1" name="qty_{$product.id_product|intval}" id="quantity_to_cart_{$product.id_product|intval}" class="text" value="{if isset($quantityBackup)}{$quantityBackup|intval}{else}{if $product.minimal_quantity > 1}{$product.minimal_quantity}{else}1{/if}{/if}" /> <a href="#" data-field-qty="qty_{$product.id_product|intval}" class="btn btn-default button-minus product_quantity_decr" style="clear:none;"> <span><i class="icon-minus"></i></span> </a> <a href="#" data-field-qty="qty_{$product.id_product|intval}" class="btn btn-default button-plus product_quantity_incr" style="clear:none;"> <span><i class="icon-plus"></i></span> </a> And minimal quantity is shown, but I don't think my modification is the problem, because it was the same problem before I made it. On the other side, I have made modification on product.js for the product site to have multiply quantities: // The button to increment the product value $(document).on('click', '.product_quantity_up', function(e){ e.preventDefault(); fieldName = $(this).data('field-qty'); var currentVal = parseInt($('input[name='+fieldName+']').val()); if (!allowBuyWhenOutOfStock && quantityAvailable > 0) quantityAvailableT = quantityAvailable; else quantityAvailableT = 100000000; if (!isNaN(currentVal) && currentVal < quantityAvailableT) $('input[name='+fieldName+']').val(currentVal + minimalQuantity).trigger('keyup'); else $('input[name='+fieldName+']').val(quantityAvailableT); }); // The button to decrement the product value $(document).on('click', '.product_quantity_down', function(e){ e.preventDefault(); fieldName = $(this).data('field-qty'); var currentVal = parseInt($('input[name='+fieldName+']').val()); if (!isNaN(currentVal) && currentVal > 1) $('input[name='+fieldName+']').val(currentVal - minimalQuantity).trigger('keyup'); else $('input[name='+fieldName+']').val(1); }); And on product side it works perfectly. Do you know what I'm doing wrong? Maybe I have to add something else? Or in the other place? Please answer.

Hi, do you know how can I change this code if i have also multiply quantities? (I'm selling product by packs, for example by 6,12,18 etc.) I have made the modification for product page, but I can't do it for my product list. So far I have made code that allow to show minimal quantity on product list, but my plus and minus button are still adding +1 and -1 when minimal quantity is added. So I suppose I have to make $('input[name='+fieldName+']').val(currentVal + MinimalQuantity).trigger('keyup'); instead of $('input[name='+fieldName+']').val(currentVal + 1).trigger('keyup'); but it isn't working. Please, help me.
