--Sorry if this script doesn't work, my Studio is broken to I can't test any scripts., so I'm scripting from memory.

local NotTouch=true
script.Parent.Touched:connect(function()
if script:FindFirstChild("WHATEVER NAME HERE") and Touch then
NotTouch=false
repeat wait(1)  script.WHATEVERNAMEHERE.Value=script.WHATEVERNAMEHERE+1 until nil --You can change nil to the amount you want it to stop at
end end)
script.Parent.TouchEnded:connect(function()
NotTouch=true
end)
