[SOLVED]Why it doens't jump the playerK? ERROR: Attempt to index field 'Jump'(a boolean value)

I want if locked is true that the player jumps? But it isn't working... It's a serverScript

script.Parent.Parent.DriveSeat.ChildAdded:Connect(function(child)
	if script.Parent.Value == false then
		return
	elseif script.Parent.Value == true then
		if child:IsA("Weld") then
			if child.Part1.Name == "HumanoidRootPart" then
			local player = game.Players:GetPlayerFromCharacter(child.Part1.Parent)
			player.Character.Humanoid.Jump = true
			end
		end
	end
end)

First take a look at the error in the title and the error is at line 9...

character.Humanoid.Jump does't have a Value, it is a value itself, You just need to do character.Humanoid.Jump = true
