Hey, I have a problem to add the fees using ajax on cart page.
On my cart I have added one checkbox. If checkbox checked then the fee add to the cart and updated the cart totals.
But right now, its' added to cart but on checkout the fees removed.

how to make to choose value option from select list? :)

I got this working so that the fee is properly assessed and the customer pays the new total including the fee. I actually want to pass that fee on to the vendor. How would I go about adding that to the total they are able to withdraw?
