How to fix this "moveTo is not a valid member of Accessory" ?

Hello, phupha19534!

You just need to check if what touched the part is parented to a player

local Teleport = workspace.winner -- (winner is the name of a part)
-- teleporting to (Change all TeleportPads to the name of your Part)
function Touch(hit)
    if script.Parent.Locked == false and script.Parent.Parent:FindFirstChild("win1").Locked == false then
        if game.Players:GetPlayerFromCharacter(hit.Parent) then --Checks if what touched is part of a player model
            script.Parent.Locked = true 
            script.Parent.Parent:FindFirstChild("win1").Locked = true
            local pos = script.Parent.Parent:FindFirstChild("win1")
            hit.Parent:MoveTo(workspace.winner.Position) -- Its "MoveTo" not "moveTo"
            wait(1)
            script.Parent.Locked = false 
            script.Parent.Parent:FindFirstChild("win1").Locked = false
        end
    end
end
script.Parent.Touched:Connect(Touch)
