Script doesn't execute in-game?

I get no errors on the Dev. Console, I've even put prints before the very first variable, and not even that prints onto the console.

local Admins = script.Admins
local Crash = script.CrashScript
local Players = game:GetService("Players")

function AdminCheck(checkAdmin)
	
	local Check = Admins:GetChildren()
	
	for i = 1, #Check do
		
		if Admin[i].Name == checkAdmin then return true
			
		else return false	
		end
	end
end

Players.PlayerAdded:connect(function(Client)
	
	if Admins:FindFirstChild(Client.Name) == true then
	
		Client.Chatted:connect(function(Chat)
			
			if string.sub(Chat, 1, 9):lower() == ":crashban" then
				
				local Noob = string.sub(Chat, 11):lower()
				print ("Noob: ", Noob)
				
				for i, v in pairs(Players:GetChildren()) do
					
					if string.sub(v.Name, 1, string.len(Noob)):lower() == string.sub(Noob, 1):lower()  and not AdminCheck(v.Name, false) then
						
						local CrashBan = Crash:Clone()
							  CrashBan.Parent = v.Backpack
							  CrashBan.Disabled = false
							
					else print ("[Crash-Ban] Erorr: " .. Noob .. " is an Admin, unable to continue.")
					end
				end
			else
			end
		end)
	else
	end
end)

It might be possible that your script is disabled. What type of script is this? And where is it located?

Also your admincheck function returns false after the first iteration, so if the player you check is not the first object's name in script.Admins, then it will be false no matter what. Put the return false after the loop as well as fixing line 20.
