one JS script not working when removing another script

Hello,

I am using a simple script that adds classes to a menu item. I am also using other scripts such as selectnav, jqueryUI effects, fancybox in spearate files/

I am not using the Fancybox after all, but when I remove the script from enqueue script, the add class fucntion no longer works.

I have almost no knowledge in JS therefore I am litterly unable to resolve this problem 🙁 Although I am pretty sure it’s nothing…

Thanks in advance for your help
