Cr3ativ Portfolio filter function

Hello!
First of all – I like your portfolio a lot. It’s exactly what I was looking for. Thank you!

Now to my question. I’m building a wordpress site and uses the Cr3ativ Portfolio with three columns and filter, but I can’t get the filter function. I have followed your instructions and everything else seems to work but not the filtering function.

Here is my website:
http://dev.gislavedssymfoniorkester.se/konsertprogram/
(It’s in Swedish but I hope you can understand whats wrong anyway.)

Thanks!
