How do I create a dmg brick without it interfering with my healing brick?

So I have 2 bricks, both have the same script, but one does damage and the other heals

When I touch the damage brick I lose the 10 hp I tell it to take away And when I touch the heal brick I heal my health back

The issue is that after healing I go and touch the damage brick and it takes away way more then 10 health

What I believe the issue is, is that when the damage code goes into affect it saves the value that
the health was at after it damaged it Then when the heal code adds more health, the damage code reset the health back to where it saved it and starts damaging it from there

Damage Script(Normal Script):

local debounce = true

script.Parent.Touched:connect(function(hit)
    if debounce then
        debounce = false
        local ply = hit.Parent
        local h = ply:FindFirstChild("Humanoid")
        local dmg = 10
        if h then
            h.Health = h.Health - dmg
            wait(1)
            debounce = true
        end
    end
end)

Heal Script(Local Script):

local debounce = true
local functionstarted = false
print 'script?'

while true do
    wait()
    if functionstarted == false then
        script.Parent.Touched:connect(function(hit)
            functionstarted = true
            print'function started'
            if debounce == true then
                print'debounce activated'
                debounce = false
                local heal = game.Players.LocalPlayer.PlayerGui.        
                           Classes.Healer.Abilities.HealCircle.
                           HealthPerSecond.Value
                local CharHe = game.Players.LocalPlayer.
                             Character:WaitForChild("Humanoid")
                if hit.Parent == game.Players.LocalPlayer.Character then
                    print'humanoid found'
                    if CharHe.Health < (CharHe.MaxHealth/100 * 97) then
                        print'healing began'
                        CharHe.Health = CharHe.Health + 
                                        (CharHe.MaxHealth/100 * heal)
                        wait(1)
                        functionstarted = false
                        debounce = true
                    end
                end
                if not hit.Parent then
                    print'humanoid missing'
                    functionstarted = false
                end
            end
        end)
    end
end
