I'm trying to set this up so at a specific key-frame a ray is fired a couple of studs away from the player and if the ray intersects another player it'll damage them but the ray-cast function is telling me my identifier is a nil value

my pre-function locals are: 

local animation
local player = game.Players.LocalPlayer
local drop_kick = Instance.new("Animation")
local playercore = player.Character.LowerTorso
local Rfoot = player.Character.RightFoot

drop_kick.AnimationId = ("rbxassetid://[code]") -- loads animation fine (censored the ID)

Core Script

game:GetService("UserInputService").InputBegan:connect(function(KeyInput)


if KeyInput.KeyCode == Enum.KeyCode.V then
		if not enabled then
			return
		end
		enabled = false
		local thrust = Instance.new("BodyPosition",playercore)
		thrust.maxForce = Vector3.new(280000, 1, 280000)
		thrust.position = playercore.Position + playercore.CFrame.lookVector  

		animation = player.Character.Humanoid:LoadAnimation(drop_kick) 
		player.Character.Humanoid.WalkSpeed = 0
		animation:Play()
		animation.KeyframeReached:connect(function(KickActive)
			local kickray = Ray.new(Rfoot.Position + Rfoot.CFrame.lookVector.unit * 15)
			print("Ray fired, congrats :^)") -- fires a ray when the apex keyframe of the animation is played, this also works fine
			local ignore = player
			local blip, position = game.workspace:FindPartOnRay(kickray, blip,  ignore)
			----------------------------------------------------------------------------------
			if blip.Name == "LowerTorso" then    --- i get an error here "attempt to index local "blip" a nil value despite identifying it on line 31
				return position
			else return
				end
				local humanoid = Rfoot.Parent:FindFirstChild("Humanoid")             
				
				if not humanoid then
					humanoid = Rfoot.Parent.Parent:FindFirstChild("Humanoid")
				end
				
					if humanoid then
					humanoid:TakeDamage(30)
					print("WHAMMO")
				end
				
				end)
		-------------------------------------------------------------------------
	wait(0.4)
		thrust:Destroy()
		wait(3)
		player.Character.Humanoid.WalkSpeed = 16
		print("Cooldown")                              -- works fine too
		wait(6)
		enabled = true
		print("DropKick Ready")
	end
end)

I gave a good look at the ray-casting links from the wiki such as the following:

http://wiki.roblox.com/index.php?title=Making_a_ray-casting_laser_gun

http://wiki.roblox.com/index.php/Raycasting

http://wiki.roblox.com/index.php?title=API:Class/Workspace/FindPartOnRay

-- The ray actually confirmed to fire in the output via the print() that I assigned, my only issue is the detecting factor is telling me the part i'm looking for is a nil value.

I'm at a loss as of how to fix this, if any of you can aid me in finding a fix for this and perhaps provide some further insight i'd be incredibly grateful :^)
