Why is my 'Control Points' script erroring?

I have conducted allot of tests to try and get the script to work, but it keeps erroring each time, it worked perfectly fine yesterday, but now it broke, now before you guys thumbs down this [like you did the last time], this was originally a project someone and I were working on, but the other person abandoned the project and I decided to keep it going, this script was ,INFACT, made 100% by me, TheeDeathCaster/TheAlphaStigma [Just a heads up, this was not stolen NOR copied], moving on, the Output keeps saying 16:34:57.303 - Workspace.MainScript:49: bad argument #2 to '?' (Vector3 expected, got userdata) 16:34:57.304 - Script 'Workspace.MainScript', Line 49 - upvalue SetSpawn 16:34:57.305 - Script 'Workspace.MainScript', Line 81 - upvalue BalanceTeams 16:34:57.305 - Script 'Workspace.MainScript', Line 96 - local Leader 16:34:57.306 - Script 'Workspace.MainScript', Line 111 16:34:57.307 - Stack End, but I do not know what it means by that, nor how to fix the problem, here is the script [I have commented all current errors where they happen];

Why did I post the whole script, you may be wondering? I was told before on an old question to post the entire code for a better understanding. :P Control Points game
