I'm desesperating for this or other scrip like this to work

[sima...@gmail.com]

I'm trying to solve this issue but I need to have a external page with modal code like the exemple but I can't solve the problem as the Javascrip and CSS are on other page from the modal where the select option is.

How to solve?
