Can't mount network drive (cifs).

I've installed LMS on RPi3B+ (Picoreplayer 4.1.0). I can't mount network USB HDD drive attached to my router and shared. Share type is CIFS. I don't understand what is Mount Point. Is it a folder where my music is located? The HDD name is SILICON_640, the folder with music is AUDIO.
Help me, please!
What am I doing wrong?
