Bootstrap popup not opening. What to do?

Question

Drupal

Site on drupal 7. Layout
was performed using bootstrap.
When you click on the first button, a modal window should pop up. Instead, it opens for a split second and closes immediately.
Perhaps there is some kind of script conflict, but I do not understand JS so well that I can immediately see it.
The site is at .
Help, please, to understand!

Answer 1

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>

Try to connect this library, it should work.

Answer 2

I had it. Cause... Two scripts are connected. bootstrap.min.js and modal.js. in bootstrap.min.js modal window is already implemented.
The script worked twice: first it opens and immediately closes, because the window is closed and the button of the modal window was pressed.
One of the scripts turned off and everything worked.
