Add to cart adds wrong product

-- url of the page with the problem -- : www.digitalguarddawg.com/rv/rv-1000/product
-- HikaShop version -- : 2.2.2
-- Joomla version -- : 2.5.16
-- PHP version -- : 5.3.x
-- Browser(s) name and version -- : Chrome

I have 3 tabs under the product on this page. Accessories lists 2 allied products to the main unit. If you click Add to cart for the main product it just adds the first product under the accessories tab.

I have an identical type of set up here - www.digitalguarddawg.com/automobiles-tru...motive/pbs-i/product - and it performs as expected.

Hi,
It's maybe a cache issue, can you disable the Joomla cache, and clear it ? You'll also have to disable it in the joomla config, and unpublish the cache plugin.

Definitely NOT the cache. It isn't on and never was.

The other pages that are working correctly are actually under this page (not the link as previously given) so I know it can work...

www.digitalguarddawg.com/motorcycles/rfi...y/dgd-kim-hd/product

Inspecting the button with Firebug shows:

<input type="submit" class="btn button hikashop_cart_input_button art-button" name="add" value="Add to cart" onclick="var field=document.getElementById('hikashop_product_quantity_field_1');if(hikashopCheckChangeForm('item','hikashop_product_form')){ return hikashopModifyQuantity('405',field,1,'hikashop_product_form','cart'); } else { return false; }" style="zoom: 1;"/>

Sorry Jerome, I am really going to have to disagree. I have it working correctly on the very same site on this page (look under Harley Accessories tab):

www.digitalguarddawg.com/motorcycles/rfi...y/dgd-kim-hd/product

The DGD-KIM-HD can be added to the cart correctly, although, despite the setting to the contrary, after adding to the cart the user is taken to the checkout. That's less of an issue, though I would rather it didn't.

However, the fact remains, this page adds correctly to the cart and www.digitalguarddawg.com/rv/rv-1000/product does not despite being set up in exactly the same way.
