Need Add ScrollBar to Ready Project

I'll be thankful if someone helps me. I have to add ScrollBar to my project ( photo and code below ). Scrollbar must be related with progress bar - when scrollbar has low value, progressBar is slower, and when scrollbar has greater value, progressBar is faster. Scrollbar must be horizontal, located above the progressBar.

Thank a lot !
