The script itself doesn't destroy itself?

I tried making the trigger part do their function and stuff, after .97 seconds, the script doesn't destroy itself, but the functions came in. I wonder what I have done wrong at this point?

script.Parent.Touched:connect(function(hit)
	script.Sound:Play()
	script.Parent.Parent.DoorClose.Union.Transparency = 0
	script.Parent.Parent.DoorClose.Union.Part.PointLight.Enabled = true 
	script.Parent.Parent.DoorClose.Union.Part.Transparency = 0
	script.Parent.Parent.DoorOpen.Union:Destroy()
	script.Parent.Parent.DoorOpen.Union.Part:Destroy()
	wait(.97)
	script:Destroy()
end)

Nvm, I fixed it thanks to greatneil80. I added debounced and it worked out smoothly.

There is a disabled property in scripts. Simply do this. Is this what u needed?

script.Parent.Touched:connect(function(hit)
    script.Parent.Script.Disabled = false
    script.Sound:Play()
    script.Parent.Parent.DoorClose.Union.Transparency = 0
    script.Parent.Parent.DoorClose.Union.Part.PointLight.Enabled = true 
    script.Parent.Parent.DoorClose.Union.Part.Transparency = 0
    script.Parent.Parent.DoorOpen.Union:Destroy()
    script.Parent.Parent.DoorOpen.Union.Part:Destroy()
    wait(.97)
    script.Parent.Script.Disabled = true
end)
