Script works in studio test but not in the actual game?

This script is supposed to play a sound when touching a brick, while stopping other sounds

script.Parent.Touched:connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid")then
	game.Players[hit.Parent.Name].PlayerGui.Sound1.Volume = 1
	game.Players[hit.Parent.Name].PlayerGui.Sound1:Play()
	game.Players[hit.Parent.Name].PlayerGui.Sound2:Stop()
end
end)

However, when tested on roblox studio it works perfectly fine but when in the actual roblox game it fails to do anything.

I'm new to scripting so it's been a pain trying to figure out whats wrong with this script, please send help!

Try using GetPlayerFromCharacter, like so:

script.Parent.Touched:connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid")then
    player = game.Player:GetPlayerFromCharacter(hit.Parent)
    player.PlayerGui.Sound1.Volume = 1
    player.PlayerGui.Sound1:Play()
    player.PlayerGui.Sound2:Stop()
end
end)
