Please help me. the Output said it could not create CollisionGroup
script.Parent = game:GetService("ServerScriptService")
local PhyService = game:GetService("PhysicsService")
local PlayerGroup = PhyService:CreateCollisionGroup("p")
PhyService:CollisionGroupSetCollidable("p", "p", false)

I would call for the group first...but does the output just say Could not create, or Could not create, group already exists?
Could not create
Is this the whole script? You need to call for the service first, add the parts, then create the group
