Developer help

I have made a few glide apps in the past but I am stuck with this one. I am making a summer workout app for my basketball team that I coach. I am having trouble connecting Multiplayer tracking- daily workout assignments- multi drills accounting.
The problem probably exists in my limited spreadsheet knowledge and limited coding knowledge. I would love for someone to look at my app and open the door where I am stuck. I just cannot tie the three components together Multi players- daily workout assignments- multi drills per workout and tracking.
Any help would be appreciated. I can pay anyone for their time if needed… Here is my contact or 505-249-2968
