Javascript error in module

There were a couple, actually. The first was a "jQuery is undefined" error, but we got around that by loading jQuery manually before the calls to the Mashup scripts (if we let joomla load everything, the Mashup scripts get loaded before jQuery). The one I'm writing about, however, we can seem to get around. Nothing shows up on the page where we have the module loading, but in the console, we see the following:

10:02:45.316 TypeError: $container.mixItUp is not a function[Learn More] nonprofit-profiles:982:17

How can we solve this so we can actually use the module?

Dear Customer,

Thank you for using our product and I am sorry for my late reply.

As your request, pls send me your website's info including URL and admin account via email address This email address is being protected from spambots. You need JavaScript enabled to view it. so that our DEV can check and deeply understand your problem.

All your info will be kept private, for sure. Look forward to hearing from you soon.

Best regards,
Hieu

Here's the info you need.

site: dev.solowebdesigns.com/dyson/administrator/
(oops, didn't see the "mail it to..." part)

I included that in the email, but the module is loaded on this page: dev.solowebdesigns.com/dyson/nonprofit-profiles

It does appear to be working now, however, the list doesn't seem to collapse as it should when you filter the list of posts (for example, selecting Economic Vitality). You get a single column running down the page instead of a grid.

EDIT: I also noticed that when you select any of the tags to filter the list, it doesn't actually hide the posts that don't belong to that filter.

We need to know what you did to fix this, as we have just moved to the live server for this site, and it's doing the same thing it was doing on the development server.
