Why is my 'Control Points' script erroring?

I have done a few changes to the script, but it keeps erroring, the Output keeps saying 15:54:57.175 - Workspace.MainScript:43: bad argument #2 to '?' (Vector3 expected, got userdata) 15:54:57.176 - Script 'Workspace.MainScript', Line 43 - upvalue SetSpawn 15:54:57.177 - Script 'Workspace.MainScript', Line 71 - upvalue BalanceTeams 15:54:57.178 - Script 'Workspace.MainScript', Line 86 - local Leader 15:54:57.179 - Script 'Workspace.MainScript', Line 101 15:54:57.180 - Stack End, but, I don't know what to do anymore to fix it, it keeps saying this error everytime in Edit mode and Online mode [this just started recently, yesterday it worked fine], here is the script [I know, it's really messy coding ;-;];
