Help Varest spawn effect!

I have added a do once but then it does " only once" while I want it to not spawn while there is already a character spawned but if I get a new action value of “1” from Varest I want to spawn it but only if there isn’t already one spawned.

Also I get this error when I close session on my previously showed setup …

This is because I want to delete the character after the value goes to 0 …
