I have two Jquery scripts , I need to load them into a single page

The scripts work fine separately , but when I try to load them into single page, only one of them works

this is my code for loading the two scripts:

2. $(document).ready(function(){
4.        //Load the second page and second page script
5. $('#firstContainer').load('secondPage.html');
7. $.getScript("js/secondPageScript.js");
8. 
   
9.        //Load the thirdpage and third page script
10. $('#secondContainer').load('ThirdPage.html');
11. $.getScript("js/ThirdPage.js");
14. });
