how do i make localscript change values both at server and client?

im making an horror game that is some sort fan game of fnaf, so i made 2 buttons(hide and unhide) hide teleports you under table and unhide teleports back to chair. both are textbuttons with localscripts(regular wont work) ive made that theres an hiding value, so if you are hiding its 1 and if not its 0. if its 0 you get a jumpscare. hide button supposed to change it to 1 but it only change it in client. if i try server it isnt changed. i would also like to get help with building and scripting heres script of hide

wait(1)
player = game.Players.LocalPlayer
button = script.Parent
local debounce = false

function helpme()
 if not debounce then

 debounce = true
 LowerTorso = player.Character.LowerTorso
 LowerTorso.CFrame = game.Workspace.teleporters.tele2.CFrame
workspace.telepart4.Value.Value = 1
 end
end
button.MouseButton1Click:connect(helpme)

while true do wait()
debounce = false
wait(7.5)
end
