That is a great question! What is blocking the script to run properly - hence - saving the changes is the fact that you have broken your tag into few lines of code. You currently have a line that goes:
Having that broken into 2 lines is causing the error, as html tags cannot be broken that way and have to be in one line. Same thing goes to script that goes from line 14 to 18 - you have script broken with new lines. Please make sure that one function/script is within one line and let the editor to wrap the code itself. That should do the trick and fix your website.
If you will still have problem please post your code here (make sure to wrap with the code button, see below) and I’ll do my best to help you out :)
