What's wrong with this If/Else Statement?

This statement isn't working or returning any errors. I posted more of the code below the problem lines if you need to look at it.

if humanoid then
    coroutine.resume(coroutine.create(function()
        hitPart.Decal:Destroy()
        particles.Texture = "rbxassetid://233246818"
        particles.Enabled = true
        wait(1)
        particles:Destroy()
    end))
    humanoid:TakeDamage(damage)
    print(damage)
else
    coroutine.resume(coroutine.create(function()
        particles.Texture = "rbxassetid://233246818"
        particles.Enabled = true
        wait(1)
        particles:Destroy()
    end))
end

Either way if humanoid exists or it doesn't it should change the texture of the particles and enable them. However it does not do either. When looking at the code below, hitPart is created and placed, decal is created, particle emitter is created.

--All of needed code below this line--

hitPart = Instance.new("Part")
            hitPart.Anchored = true

            hitPart.Parent = workspace.IgnoreModel
            game.Debris:AddItem(hitPart,7)
            local decal = Instance.new("Decal",hitPart)
            decal.Face = "Front"
            particles = Instance.new("ParticleEmitter",hitPart)

            elseif hit.Parent.Parent:FindFirstChild("Humanoid") then
                humanoid = hit.Parent.Parent.Humanoid
            else
                humanoid = nil
            end

                humanoid:TakeDamage(damage)

            else
