I am caught in a trouble. I have set up the store with foxycart checkout but now we want to add amazon checkout too.
For doing this, i am facing troubles.
There are 3 products which has 3 different forms with separate submit button and that is hidden too.
Now when i try checkout by amazon, only first product is going to checkout and if i select only second product and submit it via that product form's hidden submit button, it is throwing cart validation error as quantity_hash_present. And if i select first product quantity and process by second product submit button, it is going further with first product.
Am i missing something? Can you tell me what is the exact problem..
