Slicknav/jQuery not loading in childtheme

Hi!

Let me start of by telling you that I d’ont excatly know what Im talking about, but Im googling around and searching here on the forums for solutions. And thats why i think the jQuery script or what may be wrong might not be loading. So i know how to google up code, replace it and understand a bit how it works. But no more then that.

Im using the Solo theme, and when Im activating the parent-theme the navbar works when going lower then 800px width. But when my childtheme is activated this does not work at all. I also tried to download the Plugin Slicknav, but after hours of trying different things last night I couldnt even figure out my CSS menu class/ID and i went to bed :).
So could the problem be with this or could it be something else?

My site is not public, but I havnt changed anything regarding my menu from what I know that could interfere.

Here is my function.php from the childtheme, no changes more then adding the themes name which I found somewhere i should do.

If you need me to describe something more or show you any other code, please tell me and i will fix it since my site is not public atm. Thanks!
