Debounce Problem (I think)?

Ive made stairs which should go up and down, it goes up when i press the button. I want it to go down when i press the button again. Why isnt it working?

Stair1 = script.Parent.Parent.Stair1 --All the variables
Stair2 = script.Parent.Parent.Stair2
Stair3 = script.Parent.Parent.Stair3
Stair4 = script.Parent.Parent.Stair4
Stair5 = script.Parent.Parent.Stair5
Stair6 = script.Parent.Parent.Stair6
Stair7 = script.Parent.Parent.Stair7
Stair8 = script.Parent.Parent.Stair8
Support1 = script.Parent.Parent.Support1
Support2 = script.Parent.Parent.Support2
Support3 = script.Parent.Parent.Support3
Support4 = script.Parent.Parent.Support4
Support5 = script.Parent.Parent.Support5
Support6 = script.Parent.Parent.Support6
Support7 = script.Parent.Parent.Support7
Support8 = script.Parent.Parent.Support8


value = script.Parent.Value
var = 0
local debounce = false
function onClicked(playerWhoClicked) --Checks if button is clicked
    if not debounce then
        if value.Value == false then --Is the value == false?
            debounce = true

script.Parent.ClickDetector.MouseClick:connect(onClicked)

It prints "Done" also it changes the Value to true after.
