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"

        --local shirt=s:clone()

        --p:remove()
        --s:remove()

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
