Dear People,

I have a big issue with the checkout. The subtotal is not oke when i have 2 options into the cart and 1 under optoin of the same parant product.

We have also a dutch site and there is the same isue and we have a different system.

.com we have on option and then characterics
on the nl we have direct chractereics.

This is no product config fault. There is something giving this error on the checkout page. How i can solve this? This a live site and important it works oke

I hope you can help me. Check picture for error

Dear Jerome,

Thanks for your reply. Yes we are Lucky to found this isue before someone make a mistake.

The Size is the only option what is price related. All other options are free.

Size 5ML is 2.40 Ex VAT and Incl 2.90 euro
When you have 1 product Menthol with free option 12 nicotine and 2 same product with the free option 20 nicotine it is:
2.90 + 5.80 =9,20 and this is wrong
2.90 + 5,80 =8,70 this oke

When you choise 2 products and then other flavour with other option this fault is not there.

This error is only when you choose the same product but with different free options. When you do this you get wrong subtotal.

See picture to see the mistake of the checkout page. It is not for 1 flavour but for all. I have create the .com version on options and the .nl site with chars and gives also the same issue. (Other Joomla instalation + Other Hikashop instalation with same problem and other structore)

Hello William,
Sorry for the late reply, I've tested your issue on my end with the same configuration and I didn't succeed to reproduce it in the 2.5.0 hikashop version.
If you're still having that issue can you :

1. Download the last hikashop version through our website, install it and test it again ?

2. If you're still having that issue, can you give us a link to your website so that we can directly check and test it ?

Thanks.
