Popup window on two buttons... How to do?

Question

JavaScript

Hello.
There is a portal - neveste.by
There is a button on the main page - registration. When you click on it, a registration window pops up.
And there is a page neveste.by/pages/price
I somehow attached a button there on my own, but when you click on it, no registration form pops up ... The question is, how to file it? -)

Answer 1

The button on top has the same id as the one you placed below it. Therefore, the pop-up window works on the id that it sees first.
You need to edit the script that calls this window so that it calls it by a different id for another button, for example. There are many options.

Answer 2

do not use elements on the page that have the same id, i.e. id must be unique and one on the page, you have 2 of them. If you want a pop-up window to be called when clicking on several elements, set different ids for them and edit the window call script or one common class.
