I'm making a Ki blast script but it doesn't damage, what's happening?

I want to do the damage from my ki blast based on enemie defense, i did almost the same thing to do a punch and it's working, but when i put the script into the ki blast, it just ignore the condition to check the enemie's defense, sorry if it's a long script:

local player = game.Players.LocalPlayer
local name = player.Name
local candamage = true


local stats = game.ReplicatedStorage:WaitForChild("stats"..name)
local power = stats:WaitForChild("power")
local ki = stats:WaitForChild("ki")
local defense = stats:WaitForChild("defense")
local kidmg = stats:WaitForChild("kidamage")
local chatting = false
local energy = stats:WaitForChild("energy")
local maxenergy = stats:WaitForChild("maxenergy")
local hold = false
local candamage = true
local touched = false
local coolE = false

 local function onKeyPress(inputObject, gameProcessedEvent)
	if inputObject.KeyCode == Enum.KeyCode.Q and coolE == false then
		
		 local human1 = workspace:WaitForChild(name)
        local human = human1:WaitForChild("Humanoid")	
        local righthand = human.Parent.RightHand
        local torso = human.Parent.HumanoidRootPart
       
       
 

		
        local blast = Instance.new("Part")
        blast.Shape = "Ball"
        blast.Parent = workspace
        blast.Size = Vector3.new(2,2,2)
        blast.Material = "Neon"
        blast.BrickColor = BrickColor.new("Cyan")
        blast.Transparency = 0.2
    
        blast.CFrame = righthand.CFrame * CFrame.new(0,0,0)
        local bv = Instance.new("BodyVelocity")
        bv.MaxForce = Vector3.new(math.huge,math.huge,math.huge)
        bv.Velocity = torso.CFrame.lookVector * 100
        bv.Parent = blast
        blast.CanCollide = false
        wait(0.04)
        blast.CanCollide = true
        energy.Value = energy.Value - 10
         
blast.Touched:connect(function(hit)
	blast:Destroy()
	local namep = hit.Parent.Name
	local humanp = hit.Parent.Humanoid
	local maxp = humanp.MaxHealth / 100
	local health = humanp.Health
	local statsp = game.ReplicatedStorage:WaitForChild("stats"..namep)
	local defensep = statsp:WaitForChild("defense")
    local dama = ki.Value / defensep.Value



if 1 < dama and dama < 1.1 and candamage == true then -- and here that stop working
	health = maxp - dama * 1
	wait(0.5)
	candamage = true
	
elseif 1.1 < dama and dama < 1.2 and candamage == true then
	health = maxp - dama * 1.5
	wait(0.5)
	candamage = true
	
	
elseif 1.2 < dama and dama < 1.3 and candamage == true then
	health = maxp - dama * 2
	wait(0.5)
	candamage = true
	
	
	elseif 1.3 < dama and dama < 1.4 and candamage == true then
	health = maxp - dama * 3
	wait(0.5)
	candamage = true
	
	
	elseif 1.4 < dama and dama < 1.5 and candamage == true then
	health = maxp - dama * 5
	wait(0.5)
	candamage = true
	
	
	elseif 1.5 < dama and dama < 1.6 and candamage == true then
	health = maxp - dama * 8
	wait(0.5)
	candamage = true
	
	
	elseif 1.6 < dama and dama < 1.7 and candamage == true then
	health = maxp - dama * 11
	wait(0.5)
	candamage = true
	

	elseif 1.7 < dama and dama < 1.8 and candamage == true then
	health = maxp - dama * 20
	wait(0.5)
	candamage = true
	
	
	elseif 1.8 < dama and dama < 1.9 and candamage == true then
	health = maxp - dama * 40
	wait(0.5)
	candamage = true
	
	
	elseif 1.9 < dama and dama < 2 and candamage == true then
	health = maxp - dama * 60
	wait(0.5)
	candamage = true
	
	
	elseif 2 < dama  and candamage == true then
	health = maxp - dama * 100
	wait(0.5)
	candamage = true
	
	
	
end

end)
   
		
		local animation = Instance.new("Animation") -- and from here it's working again
		animation.AnimationId = "http//roblox.com/?id=01335430799"
		local animTrack = human:LoadAnimation(animation)
		ki.Value = ki.Value + 5
		animTrack:play()
		coolE = true
		wait(0.4)
		coolE = false
		animTrack:stop()
		
	
		end
	
		end

	
	game:GetService("UserInputService").InputBegan:connect(onKeyPress)

And it doesn't say nothing in the output, and the whole script is working except for the damage

Do not use localscript, because that makes that ability not FE use Remotes, localscript (to activate the keyboard) and normal scripts to do it FE
