Why is the modal window not working in the slider?

Question

css

Hello.
I am making a form for ordering goods with one-click payment, which is displayed in a modal window when you click on the "Buy in 1 click" button. Here you can see _ myshop.sharelink.ru . Everything works only outside the slider block, it doesn't work in the slider itself. It turns out that the slider blocks the pop-up window, how to make friends with it?

Answer 1

I do not see in your script an event on a click on the "order" button in the slider. Is it written anywhere at all?
