Needing help with checkpoints

I’m trying to work out a checkpoint issue I am watching to see if I can change spawn points and just only having one spawn point I’ve checking my values and I seem to figure out where I’m getting stuck for checkpoint being able to switch from the starting spawn point to a different spawn point and shutting off the original spawn point

Player start has a field to put a tag, in choose player start they are a function for put the tag.
