Script works in studio-solo, and in build, but doesn't work in actual game....?

game.Players.PlayerAdded:connect(function(player)
	player.CharacterAdded:connect(function(character)
		I = Instance.new("NumberValue")
		I.Name = "Position"
		I.Parent = player.Character
		wait(3)
		local shirt=player.Character:findFirstChild("Shirt")
		local pant=player.Character:findFirstChild("Pants")
		--local shirt=s:clone()		
		--local pant=p:clone()
		--p:remove()
		--s:remove()
		local jump=Instance.new("Animation")
        jump.AnimationId = "http://www.roblox.com/Asset?ID=168805279"
        local animTrack = player.Character.Humanoid:LoadAnimation(jump)
		if player:IsInGroup(1129497)then
		if player:GetRankInGroup(1129497) == 240 then 
        animTrack:Play()
		pant.PantsTemplate="http://www.roblox.com/asset/?id=165541507"
		shirt.ShirtTemplate="http://www.roblox.com/asset/?id=165541475"
		end
		if player:GetRankInGroup(1129497) == 241 then 
        animTrack:Play()
		pant.PantsTemplate="http://www.roblox.com/asset/?id=165541507"
		shirt.ShirtTemplate="http://www.roblox.com/asset/?id=165541475"
		end
		if player:GetRankInGroup(1129497) >= 250 then 
        animTrack:Play()
		pant.PantsTemplate="http://www.roblox.com/asset/?id=168791583"
		shirt.ShirtTemplate="http://www.roblox.com/asset/?id=168791496"
		end
		if player:GetRankInGroup(1129497) == 230 then 
        animTrack:Play()
		pant.PantsTemplate="http://www.roblox.com/asset/?id=168791646"
		shirt.ShirtTemplate="http://www.roblox.com/asset/?id=168791526"

		if player:GetRankInGroup(1129497) == 1 then 
        animTrack:Play()
		pant.PantsTemplate="http://www.roblox.com/asset/?id=168791668"
		shirt.ShirtTemplate="http://www.roblox.com/asset/?id=168791557"

		else
        animTrack:Play()
		pant.PantsTemplate="http://www.roblox.com/asset/?id=168791668"

		end
		hat = Instance.new("Hat")
		part = Instance.new("Part")
		hat.Name = "Futuristic 12"
		part.Parent = hat
		part.Position = player.Character:findFirstChild("Head").Position
		part.Name = "Handle" 
		part.formFactor = 0
		part.Size = Vector3.new(-0,-0,-1) 
		part.BottomSurface = 0 
		part.TopSurface = 0 
		part.Locked = true 
		game.ServerStorage.Smuggler.Mesh:clone().Parent = part
		hat.Parent = player.Character
		hat.AttachmentPos = Vector3.new(0,0.78,0.425)
	end)
end)

i need it for a group place im working on, i works perfectly in solo gives the "position" number value, creates my hat, changes the shirts and pants, and runs my animation, but when on the server it only add position value and hat.... nothing else works... help? theres other scripts that are the same, work in solo but not in public... i dont know what im doing wrong

Make sure the script is RUNNING in public mode, that may be the problem it can't run or the script should be in a LOCAL script.

This happens to me soemtimes. I just take the code and put them in seperate scripts
