NSP GK5[Module mode: Bikestore Slider] - Issue with slider

Hello,
Could someone assist me to resolve the issue that I'm having with my NSP GK5 wich is set to mode Bikestore Slider ?
The issue is that the slider is not working anymore. Even if I click on both arrow(at the left and right), nothing happens.
Attached a print and this link for more information : https://astucompris.com/
Thank you in advance.

Hi

Does it work when You switch it to a different style ? Bikestore style is versy old so may not work with newer javascript libraries. Please send me an access to joomla panel so I'll check.

Hi teitbite,
even if I switch to a different style it doesn't work.

Hi

I can see You have a syntax error on Your site. This may be causing all below scripts in code to not work. Please take a look at this error on screenshot. Since I cannot recognise it, it should be something You've added.
