"attempt to index nil with number"?

hello, i've been having issues on how to save data. This is my second time using datastore so I definitely don't know what I'm doing. The error occurs at line 39, "_CENTS.Value = data[1] or 100".

local DataStoreService = game:GetService("DataStoreService")
local DataStore1 = DataStoreService:GetDataStore("DataStore1")


game.Players.PlayerAdded:Connect(function(player)
	repeat wait() until player ~= nil
	local _CENTS = game.ServerStorage.Currencys[player.Name].Currency.Cents
	local _CURRENTSTEPSTOMULTIPLIER = game.ServerStorage.Currencys[player.Name].UI_Mechanics.CurrentStepsToMultiplier
	local _CURRENTENERGY = game.ServerStorage.Currencys[player.Name].UI_Mechanics.Current_Energy
	local _CURRENTMULTIPLIER = game.ServerStorage.Currencys[player.Name].UI_Mechanics.Current_Multiplier
	local _CURRENTSTAMINA = game.ServerStorage.Currencys[player.Name].UI_Mechanics.Current_Stamina
	local _MAXENERGY = game.ServerStorage.Currencys[player.Name].UI_Mechanics.Max_Energy
	local _STAMINAMAX = game.ServerStorage.Currencys[player.Name].UI_Mechanics.Stamina_Max
	local _STEPSTONEXTMULTIPLIER = game.ServerStorage.Currencys[player.Name].UI_Mechanics.StepsToNextMultiplier		

	
	local valuesToSave = {_CENTS.Value,
		                  _CURRENTSTEPSTOMULTIPLIER.Value,
		                  _CURRENTENERGY.Value,
		                  _CURRENTSTAMINA.Value,
	                      _MAXENERGY.Value,
						  _STAMINAMAX.Value,
						  _STEPSTONEXTMULTIPLIER.Value,
	    		               }           	                             
	local playerUserId = "player_"..player.UserId
	
	local data -- A variable to assign the data to
	
	--[[
		load data
	--]]
	
	local success, errormessage = pcall(function()
	     data = DataStore1:GetAsync(playerUserId, valuesToSave)
	end)
	
	if success then
		_CENTS.Value = data[1] or 100
		_CURRENTSTEPSTOMULTIPLIER.Value = data[2] or 0
		_CURRENTENERGY.Value = data[3] or 0
		_CURRENTSTAMINA.Value = data[4] or 0
	    _MAXENERGY.Value = data[5] or 50
		_STAMINAMAX.Value = data[6] or 100
		_STEPSTONEXTMULTIPLIER.Value = data[7] or 2
	elseif errormessage then
		print(errormessage)
	end
end)

If loading doesn't error but saved data for the key doesn't exist (consider a player joining for the first time - they have no data saved), GetAsync would return nil. data would be nil in that case, and so data[1] would give that error. A default data can be given if it's nil. With your current defaulting, the default data there can be an empty table.

Don't put _CENTS.Value by the " { "

It should be like this:

local valuesToSave = {
				_CENTS.Value,
				 _CURRENTSTEPSTOMULTIPLIER.Value,
				_CURRENTENERGY.Value,
				_CURRENTSTAMINA.Value,
				_MAXENERGY.Value,
				_STAMINAMAX.Value,
				_STEPSTONEXTMULTIPLIER.Value,
                               }
