Yeah, the issue is that the script is also loading from each of your future meeting descriptions.
It was also in your default meeting description, so you were going to be inadvertently adding it to any new meeting agendas you created.
I deleted it from your default meeting meeting description.
However, you have a lot of future agendas, and I really do not consider it my responsibility to go through each meeting description and delete the problem script for you. I took care of your home page and your meeting information page for you previously, and your default description this time... that was pretty simple. However, at some point I need to draw a line and just tell you how to fix it yourself.
So, I am going to tell you want you need to do to get rid of the script from each meeting description...
Basically, you need to load each agenda, use the pencil button to edit it, go to the Meeting Description tab, click the Source button to switch to the editor's source view, and then delete everything from the <script tag to the end of the contents. Then click the Source button and click save to save the meeting description without the script. Please see below.
You will need to do this for everyone of your future agendas that *currently exist*, since they each have their own copy of the meeting description. I suspect that the script is likely in some of your old agenda meeting description, also.
