Link in full screen slider is not working (z-index issues)

hey folks,

I am working on my portfolio and for some reason I can not make my links (in each slide) work. The arrows of the slider are on top of the links and the z-index is not helping at all. My idea is that the user can click on the different links and then jump to the index page/the project section on the index page. Would appreciate some help, thanks!
