getCurrentItem not working for me - PLEASE HELP (URGENT)

Good day WIX Coding Experts. I’m faced with a situation that I need to fix before this upcoming Monday and I’m hoping you guys can assist me.

I have a few screenshots to my current issue and would appreciate it if you can assist me in writing the code so I can place it in my site and launch website by Monday (Deadline).

I’ve opened up a few cases and the information that is being relayed is conflicting and not consistent and maybe i’m doing something wrong. But each time the reps have put me onto a new path and I feel lost at the moment.
