Hello fellow scripters! i was wondering what was happening to my "seat" in roblox studio?

Hello, i am making a hot air balloon in roblox studio and when i created a "seat" and put it in the hot air balloon i made script for moving it all, no problem with that, but i DO have a problem with the sitting, i looked at other designs, none have to do with the player sitting in seat, with my balloon, when someone sits in it, and the balloon is moving up, the seat moves up too but the player stays in place, still seated, i dont know how this happens but its no computer glitch, its on both my computer and laptop, please help me to make the seats go up as well as the person in it! thanks everyone :) Oh bye the way, just so you know; if you stand in the hot air balloon when its rising, it brings you, its just the seat that doesnt bring the player up :/ heres the script

    if script.Parent.Parent.Parent.Barrel.Fire.Enabled == true then

script.Parent.Parent.Parent.Canopy.CFrame = script.Parent.Parent.Parent.Canopy.CFrame * CFrame.new(0,0.5,0)
script.Parent.Parent.Parent.Seat1.CFrame = script.Parent.Parent.Parent.Seat1.CFrame * CFrame.new(0,0.5,0)
script.Parent.Parent.Parent.Seat2.CFrame = script.Parent.Parent.Parent.Seat2.CFrame * CFrame.new(0,0.5,0)
script.Parent.Parent.Parent.Seat3.CFrame = script.Parent.Parent.Parent.Seat3.CFrame * CFrame.new(0,0.5,0)
script.Parent.Parent.Parent.Seat4.CFrame = script.Parent.Parent.Parent.Seat4.CFrame * CFrame.new(0,0.5,0)
script.Parent.Parent.Parent.buttondesk.CFrame = script.Parent.Parent.Parent.buttondesk.CFrame * CFrame.new(0,0.5,0)
script.Parent.Parent.Parent.trapdoor.CFrame = script.Parent.Parent.Parent.trapdoor.CFrame * CFrame.new(0,0,-0.5)
