Hello, I'm fairly new to SharePoint. My knowledge is minimal. I've recently began to try to make an appointment signup for my work center. My issue is with the choice column I am using for users to select the time of their appointment. Im struggling to find a way to remove choices as they are selected so other users can't select the same time slot. I'd imagine its certainly doable via column formatting but Im not familiar with how it works.
What I've tried to do is use MS Forms paired with choice eliminator. It would work; however, my business has security measures in place not allowing me to download google extensions. If anyone could help it would be greatly appreciated. thanks!
