[SOLVED BY ME] Attempt to concatenate Instance with string? (in a normal script, remoteevent script)

Please help with this

Code:

game.ReplicatedStorage.AdminPanelEvents.RankPromotion.OnServerEvent:Connect(function(PlayerToGiveRankTo, Reason, Rank)
	print(PlayerToGiveRankTo.."'s has been promoted to "..Rank.."!")
	game.Players:FindFirstChild(PlayerToGiveRankTo).leaderstats.Rank.Value = Rank
end)

the error is on the line "game.Players:FindFirstChild(PlayerToGiveRankTo).leaderstats.Rank.Value = Rank"
