Hi, I have project based on a barber shop
- Users get added as Customer of the store when they join click Join Quue
- Current index of customer is assigned as the data field of Position.
- When a new customer is added, i want to be update the existing customers’ Position with their new current index
Note: Same with when customer is removed that is infront of them in the queue, since their position will be changed. That why, I can call from the database the current user’s position from another screen.
I have tried alot of methods, but have all failed. Is this perhaps a Custom Event. Also, how do i trigger an update off the entire dataset not just one field?
Thanks in Advance
