My script isnt giving the player coins when they shoot a zombie, can someone help?

Here is the script that isnt working: (ps everything else works)

script.Parent.MiniGunEvent.OnServerEvent:Connect(function(Player, MouseTarget)
	MouseTarget.Parent.Humanoid:TakeDamage(5)
	Player:WaitForChild("leaderstats").Coins.Value += 1 * Player:WaitForChild("leaderstats").Multiplier.Value * Player:WaitForChild("leaderstats").Rebirths.Value 
	local Attacker = MouseTarget.Parent.AttackerPos
	Attacker.Value = Player.Character.HumanoidRootPart.Position
end)
